I have a 3.2, 90k miles, threw a misfire cylinder 1 error (and it was noticeably misfiring). Took it in and had a coil replaced (I had one burn out last year), threw the same, Spark plug and injector have been replaced and it's cleared and now there is misfires on 2, 3 and 6 along with a physical, noticeable misfire.

Idle is smooth, misfire is on slightly harder acceleration. Misfire stops as you lift.

It's been a bit noisy for a year or two but not tractor-noisy.

Any experiences of similar or suggestions where to look next?

I have just bought an injector rebuild kit off of amazon for £15 (includes delivery). It contains 12x o rings and 6 microfilters. Get yourself a set and get that fitted and run a bottle of injector cleaner on a low tank. That should sort any injector issues unless they are physically failing.

Before spending any money though, give it a compression test.

Edit - Just saw this was for a 159 so a GM engine so the above may not be as helpfull. Being a direct injection engine the injectors are probably a bit different from the Busso 3.2

The original post is already old, but 3 weeks ago the following began to happen sporadically to me, all of a sudden this list of errors in diagnostics:
  • Cylinder 6 or 3 or both "injector Circuit High"
  • Cruise Control Multi - Function Input A Circuit
  • Random / Multiple Cylinder Misfire Detected
  • Cylinder 6 Misfire Detected
  • Cylinder 3 Misfire Detected
In addition, faults on the dashboard display, such as ASR error, Cruise and failure of the fuel gauge in the tank.
This only happened in counterclockwise (left) turns .
At the time of the failure, the engine was running as tractor erratically and this problem disappeared alone after 10-20 seconds or it was necessary to stop car and turn off the engine, then restart and the irregular operation lasted for about 10 seconds after starting and then it disappeared.
At first I was looking for a problem in the main + battery cables and ground but I didn't find anything.

Finally, with the engine good running at idle I try move the cable bundles around the engine until I found a place where, after a slight movement, the described fault occurred again.
The cause of the defect was the damage of insulation on the cable harness by the sharp edge of the cylinder head under the decorative engine plastic cover around at cylinder 3 (right side of the engine at the water cooler).
Whenever exposed cables with damaged insulation touched the edge of the cylinder head, the described faults occurred.
So I covered the damaged insulation with insulating tape and wrapped the whole bundle in a piece of garden hose and secured against unwanted hose displacement with the binding tapes and thus attached it to the holder.
The original plastic cable harness holder disintegrated and so the harness rubbed against the cylinder head ...

Why do I always pick up on old topics? Can’t blame the Ipad. Still, it’s relevant to the issue - time doesn't change that.
Wonder, how many 3.2 JTS’s remain on the road today? I’d like to think the guy still had his car, but more than likely sold now or scrapped.
Today most everything is scrapped.
Often little was enough for it to work again ...
I professional repairer of TVs, PCs , but often acquaintances and friends come up with engine diagnostics, especially petrol cars bought in a bazaar.
Many times it helps to drive with the memory oscilloscope connected and then monitor the records of the individual connected sensors as the fault manifests itself because it is difficult to find out which was is first (egg or hen) and according to the oscilloscope it is possible to trace at which input the anomaly appeared first and what is appear after on control unit reactions to this anomaly.
So I know that as IQ decreases and laziness rises, more things appear on recycling (Idiocracy) :)

It's off topic, but in 2 weeks I will be mounting oil pressure sensor on this engine and placing a pressure gauge instead of a malfunctioning oil temperature gauge.
As an old school person, I know what it makes sense along with the quality of the oil I use ...
Since the temperature of the oil also decreases its viscosity and thus the lubricating ability and the oil pressure then decreases ...

You have a similar childhood and your son as I do. When I messed up my father's Panasonic radio, he realized I needed some inspiration, but without financial damage.
So he brought me an tube B/W TV from my grandmother attic :)

And under the tree, I got a transformer soldering iron and a kit for a medium-wave transistor receiver, with Russian manual with Soviet components.
Something like this, but 10 years older with Germanium transistors P401 and MP40


Then my father always came to check me after circuit breaker is shooting in home :)
Exactly this type, but 16Amps 500VAC max (SEZ Krompachy)

Then it was an avalanche, which is still not finished :)

A Superheterodyne has much greater sensitivity/selectivity than a TRF, but it is more complex to build and align. Distortion is greater too. However, in the cluttered airwaves of the West, QRM and QRN was a problem because of so much electrical interference from a multitude of sources, so you would have little chance of any quality or interference free audio with a TRF, unless you were very close to the transmitter site.

However, in the USSR, where all radio transmissions were State Controlled, frequency spacing between radio stations was much greater than in the West. So cost and simplicity were major factors and concerns over sensitivity/selectivity were not major issues. Plus, one didn’t want comrades listening to foreign; The West’s, propaganda. It was more important that Comrades were kept informed of the daily successes of the State - chances are, Uri Gagarin was listened to on these simple radios for the masses.

You are right about the properties of superhets, but why a 7-year-old boy would need quality reception and high sensitivity, and then there was never enough sound quality at AM ...
So, from my point of view, it was interesting to capture an unknown transmitter with information sent by Morze and try to read what it sends.

Maybe will be amazed, but if I look at Czechoslovak TV news today, e.g. from 1983 seems to me more objective compared by TV news today.
And why actually? Because there was talk of specific things such as which company produced how much and in what quality, where new residential houses are built and when they will be finisht, what problems are there with water for farms which areas and how they are planned to be solved, and then that the US aircraft the ship annoys the landscape on the opposite side of the globe again :)
Today, I will find out in the TV newspaper who stabbed someone in the back, who scolds whom and who the government has no money to repair highways, that the bridge built under socialism collapsed after 30 years without maintenance and in other reports about the crimes of communism. But no one will say that we live mostly in apartments that were built at that criminal time, because no one can afford new houses and flats unless he is a drug dealer or takes a mortgage with his wife for 40 years, true if he has a wife, because she to work in the UK :)

In this respect, I personally hate this system and capitalism in general.

But it is true that those who have not experienced that time and heard only one-sided information about it will not think differently than you ...
But unlike you, I can compare.

I was not stating my view on the issue.

The day to day travails of the common populous were of little concern to politicians either side of the Iron Curtain.

There is no Political Utopia, both Communism and Capitalism are systems employed by those who will always want control. And with either system there is always going to be large swathes of the Populous left behind.

There is always money about. It is how it is used and who it is that benefits from it most which is the most important factor with any system. The wealthy will always protect it by whatever means are at their disposal.

Thatcher broke up the utility/state industries on the basis that the public would become share holders in those that were privatised. A lot of those who would never consider owning shares bought at preferential rates, only to sell soon after for a “Quick Buck”.

It was a not too subtle way of transferring State assets to the already wealthy, for a song! Is this any different from how Russian Oligarchs acquired their wealth?

“Greed finds shelter in any household”.

And when those former utilities and industries are in trouble, they still come calling to the Government for Financial Support. But do they ever repay the debt? That is simply transferred to those who can least afford it. And the numbers of those disenfranchised grows - until the cycle repeats itself!

It is clear to me that a person with his traits is born the same everywhere in the sense that everyone has a list of certain traits that are more or less developed, so from my point of view it is only important which traits in which individuals are stronger and which are weaker and of course how education and the system help.
In my opinion, socialism was a relatively successful attempt to suppress qualities such as greed, selfishness, to depend at least to some extent, and instead to emphasize qualities such as belonging, collective thinking. However, it also depended greatly on what people currently ran the system.
Because some like Stalin tried to suppress these properties and others like Khrushchev or Gorbachev did the exact opposite, but you don't have to have that opinion.

I reject capitalism because he does not consider the qualities I have mentioned to be bad, but rather good qualities, without which you cannot be the best capitalist from the point of view of self-satisfaction at the expense of others :)

Despite the fact that socialism of this type disintegrated precisely due to the mistakes of leadership at the end, but the main idea was hopefully good, namely the needs of the majority in the concept, which is necessary for a more of 50 percentage of the population to have the same standard of living and this standard gradually improved.
That is why I wrote about the same housing for everyone, not of course in above-standard quality, but with all the basic needs for the longevity of the life of every individual who does not succumb to dependence on harmful substances if he consumes them regularly.
In capitalism, however, it is always only about the needs of individuals but "less successful" persons who for some reason fail to be successful (in capitalism thinking) get to the margins of society as unusable.

Thus, statistically, under socialism, 10-30% in begin and 70-80% in end of this system have the population had the opportunity to have a long life, to have a place to live, to form their family, to have an upbringing that would allow them to have a job that they enjoy.
That some individuals did not know how to use these possibilities is clear, but it is a difference from capitalism, where all those who are not successful end up in poverty at the expense of the successful ones.
Although capitalism has found that if it does not have elements of socialism, it will disappear, so there is a mixture of both types of systems, but the basic idea, namely capitalism, is still same (which is to win at the expense) and therefore this system suits only successful individuals ...

It is not that the system suits only the successful, or the oft quoted expression that "success breeds success", but that the system can, and is influenced by those who want to retain "Their" success.

Their methods are hardly conducive to the idea of a free society or indeed capitalism - per say. It has everything to do with a system which is so flawed as to permit them to succeed in maintaining economic influence, to the detriment of those that subscribe to the idea that we live in a democracy - we do not.

There are parallels with the Eastern Block - if that were not true, how would the Oligarchs acquire their wealth? It was through the influence they exerted upon society under the guise of communism, whilst it existed!

Once that changed, the only way it could continue to manifest itself was by obvious Financial Advantage as opposed to hitherto, Political.


There is little to console any Democrat, with either system.

I do not agree that the Russian oligarchs are a product of socialism or communism. These are simply the tips of the people who exist in every society as careerists cross through corpses, who also tried to change the former socialist system, and that they managed to do so with the generous help of outside influence, that is a fact.
This sort of people in Stalin era was the biggest waste, because in the Stalin era these people were labeled unreliable and could not hold senior management functions, but the later system could not prevent such people from "infecting" decomposition, which was essentially their goal. And this sort of peoples is verry difficult changed.
Even in Czechoslovakia, there were people who had their mouths full of socialist ideas, but the deeds were the opposite, and after the change of system they became modern feudal lords who still control everything that happens here in the background, so yes, there is no any democracy and there will be no.
You just have to decide what you want to support.
See the example of China, which is referred to as capitalistics economic success, but by human rights as communist.
However, the truth is somewhere in between thanks to the fact that the Chinese mentality has always thought about what is best for most of the population ...
The Russian mindset is similar, and it has nothing to do with faith or markxist-leninism. The Russian spirit of Bolshevism was there long before 1917, and there is still this kind of collective thinking.
An example is e.g. person V.V. Putin, who tries to get along with everyone in the interests of most of the country in which he lives.
It is like the 7th sense of human perception if you understand actions and are not interested in words.
Certain people simply think about how to act in the interests of the majority, but at the same time get along with everyone and convince influential individuals that they will also achieve greater success together with majority...

It is at this point I fundamentally have to disagree with your interpretation of what has happened. You seem to infer there is an Ideal which transcends human nature. Communism, and Capitalism are systems which have been set up, by; possibly idealists at the onset, but become the vehicle for the designs of those who seek control. One cannot hold that any system is an expression of the ideal, because the human species is flawed.

Oligarchs do not simply appear as if by magic when a Political system collapses, unless of course they were already in a position to exploit such a collapse as it occurred, perhaps even precipitate its occurrence.

That Putin allows this Paradigm to flourish indicates it is an inevitable necessity in retaining power. Would not the billions of Roubles improve the lot of your average Russian citizen? Yet there is extreme poverty in Russia. So Communism has moved in the same direction as Capitalism. Become a vehicle for those who will always operate behind a veil - until such times as any threat to their influence is neutralised.

The current threat to China comes by way of the protests in Hong Kong. That will ultimately be eliminated by proxy - the Hong Kong Assembly being both "Complicit and Compliant" in what Beijing seeks to achieve.

It is still unclear what Putin seeks to achieve, but for certain, neither he or the Oligarchs see Universal Suffrage as taking precedence. To change the Law to ensure he will continue to hold influence over Russian destiny, as did the the Chinese leader gives credence to nothing their political system represents.

All that is required is for them to declare themselves "Gods" as did Augustus.

If you read what I have said in my posts prior to your last, you virtually acknowledge what I am saying - it is just the way you have interpreted my meaning.

But there is no theoretical basis for one system to be more virtuous than another. Human Nature ensures that can never be the case.

If Christ were born again, They would still Crucify him!

You are twisting my words in the sense that you are connecting the oligarch with Putin. If you knew exactly what this gentleman was all about, you probably wouldn't understand it anyway.
So this gentleman and the people around him are trying to return Bolshevism in the sense of collective thinking, but they have to work with what is in the country, and this is only very gradual after Gorbachev, Yeltsin and what groups still do today. The main point is that he and his people have learned where mistakes have occurred in the past and therefore cannot and do not want to establish old socialism model, but they are trying to find compromise that prosperity will improve the lives of all, but only with what they have to available and gradual development.
But nowhere is it written that as soon as they eliminate the individuals and groups who are most harmful in this "chess" game and we call them paid helpers from the outside, they will be able to replace them. Therefore, first of all, it is necessary to create a generation of educated people as a personnel base.
After all, we all know that most of the external influences which manage and paid some people in Russia are only for the purpose of breaking the Russian Federation into small states according to the process of "divide and rule", because in teritory of RF is located the natural resources...
So if you see things from this angle, I hope you understand my position as well.

No, I’m afraid I don’t understand your position. The individual I think you are talking about, does not use rational thinking to persuade academics. And rather than debate his philosophy with his critics, chooses to dispose of them by the same means that was used before the Great Revolution.

So History repeats itself - the same mistakes are being re - enacted, which ultimately caused the USSR to collapse.

One cannot erase the distrust that has existed for so long, which makes those that do not share this gentleman’s philosophy, extremely suspicious. But the collapse of the Russian Federation was self inflicted. Re - educating the masses relies on the Teacher having a unique understanding of the subject matter.

Man!

And that my dear friend has Defied The Gods throughout the millennia!
