can you explain how you fixed your variator? cut spring or make it harder or softer or else???? please help me i have problem with gangarooing under 3000 rpm

 

[wrinx]

Doesn't sound like the variator to me...airleak, plugs, lambda, fuel pump etc etc

Is this anything to do with Marlon's thread on how to tension the belt on the 1.8 8v?

 

[marlon]

Hi 9pul.

Wrinx is right, it doesn't sound like the variator or the magnetic actuator (which is what I actually tinkered with).

Clean out the Air Flow Meter and Throttle Body with carb cleaner. If you haven't done this you will see that it is very oily in there.

Is the car kangarooing under load, or when you are travelling at a constant speed ????

Constant speed could suggest the lambda probe, but kangarooing is normally a sign of a weak mixture I think.

Check the plugs and leads (again as Wrinx said) for proper tight connections/splits etc.

We could do with a bit more info on when the car kangaroos, hot/cold/both, accelerating, constant speed etc.

cheers and welcome BTW

I didn't think the 155 8v ts had a variator

 

[wrinx]

Yes, a much more reliable one than the 16v

kangarooing,it happens when i travel at constant low speed (in traffic under 3k rpm) i have checked airflow,tps,lamda,etc.,any hole as seen on workshop manual.but everything's fine. i split lead and check it in the dark, it's fine . i use bosch F7LDCR,is it OK?

 

[9pui]

somebody said that some chip can cure it,is that true?

Hi,
This sounds exactly like the problem I still have (see Hesitation/misfire thread).
I have taken mine to an Alfa 'specialist' in SE London and they reckon there were no errors from the diagnostic check. Rather than let them loose on it, racking up hours of labour, I'm going to go through all the bits that aren't covered in the diagnostics one by one.

Hope you get yours sorted.
Rob

The best plugs to use are the Golden Lodge (original plugs). They are cheap (about £20 for 8) and they have 4 electrodes. My car runs much better with them in.

Constant speed kangarooing might still be the lambda or lambda relay/fuse. If you disconnect the lambda does the car still do the same ???

 

[kurt]

Sounds similar to the problem I had with mine last week. Took the lambda, ecu, fuel pump relays out, cleaned the contacts and replaced the fuses even though they looked ok - problem went away, ah Italian electronics......

 

[9pui]

To everybody,who has similar problem!!!!!!

today,i clean and check variator relay(nearby 3A fuse) again.
i don't know what i am thinking,till i unplug variator relay. get in car and drive..........................wow no kangaroo,now...
then i park and put relay back.
Oh no,kangarooing come back again.

now i unplug variator relay out.
i am very happy althought timing variator does NOT work..
At least, i can drive mine as smooth as it should be

however, i still wanna put relay back for full system without kangarooing, somebody know cause?? ??? please help me

Try a new relay

 

[marlon]

The relay beside the 3A fuse is for the lambda I'm sure.
If you wanna drive without the variator, disconnect the two wires from the magnetic actuator beside cylinder #1.
You will find you have absolutely no power or pull above about 3000rpm, so I'm pretty sure you have disconnected the lambda by removing the relay. You may find now that you use a lot more fuel, so replace the relay.

 

[9pui]

thank a lot,everyone

i am sure that i replace variator relay althought it besides 3A fuse.
now,i wanna put new relay for variator system, what kind of relay is suitable for variator system, is that as same as the other relay??

 

[kurt]

Someone with a parts CD on this forum should be able to tell you the number or take the relay out and copy all the numbers off it.

Unless someone corrects me, the relays are probably made by Bosch and your local parts shop will have a cross reference guide covering relays and the cars they fit on.

Do you have any breakers yards that might have 155's in that you could get one from ?

 

[9pui]

NO, i am the only one who drive 155 in my province.
that is why i have to find information from internet.
Last idea about it,manual book said variator will work when 30 persent of load and above 1600 rpm.i wonder why my variator immidiately works when i touch pedal. kangarooing happen in the same time.

do my variator work too low rpm?

 

[marlon]

It won't be the variator your mucking with. If the variator has been disconnected by removal of a relay or otherwise, you WILL know about it. The car will struggle to rev over 3500rpm quickly when under load, you will be out-gunned by 1.0litre engines....trust me, I've played about with all this stuff.

It will be the relay for the lambda probe you have removed. The lambda works at idle and at constant throttle, not when under load. That is why when you are at a constant speed the car is kangarooing (that's what you said earlier anyway). The OE relay is a Bosch part. All the relays in that area are the same (I think there are 4 of them).
