The throttle reset and ECU reset don't work for me...
I'm seeing another strange behaviour in my car (1.8 TS): when it's quite hot and the fan works frequently, the revs range between 500 and 1500 (aprox.) if the car is stopped. When the fan switches off, the revs also do that...

Any idea? Thanks!

check for spilt oil in the left side spark plug well i bought one from a guy who proud as punch said he had just done an oil change and the filler cap is very close to the left hand plug after a few weeks it would barely do 70mph. if so clean it out and replace the plug if neccasary (avoid halfords) and do an ecu reset. if not its probably lambda or MAF sensors.

Crazed

So basically the test to see if everything is working fine;
  1. Accelerate to 200 km/h
  2. All OK
  3. Problem Encountered
  4. Intervento
  5. Major Failure. Contact Dealer.
  6. Tutto OK

Another believer here!

Reset mine earlier, loads more power bottom end, better idle and temp gauge now likes staying around 90. Win!

I'm wondering if the factory reset parameter/procedure on motor ECU in FiatECUScan does the same as this better process. But it seems no more Alfa experts are coming to this thread anymore. Here I'll prove it:

..nothing? Case and point

jsv i had the exact same problem as the guy just after posted oil in the spark well is a real design fault. clean the oil out then get some silicone conductive gel. i got mine from ford as its a common ford problem. if that does not work then you will most probs need a new maf. they are a part that you will replace fairly regular every 3 years or so. also would be worth while you changing the lambda sensor which is located on the exhaust its a cheap part and also regulates the fuel air mix just like the maf.

the full ecu reset does reset the throttle so if its a throttle problem then it might do. if not and if your not to confident with checking sensors then i would take it to a local alfa garage and not main dealer. have you recently put oil in as like a post b4 oil runs into spark wells and that stops sparks from working properly. dont worry about taking the engine cover off and then other parts are just bolts also. if you take any sensor off make sure you dc the battery otherwise the cars ecu will throw a wobbler and not like it. if you dont have a clue where your maf is that would be one thing to check trace back from the air box where your air filter is and there will be a pipe with a wire coming from it just after your filter thats the maf.

Hello.

I was unable to solve my problem by doing the ECU reset (or the throttle reset). So, I bought an OBDII connector from Ebay, and with the FiatECUScan I executed the throttle reset from the software...

The result was successful: now, my 156 1.8 TS doesn't want to stall when I stop, and the rpms don't idle.

I also cleaned the MAF (discovering that my MAF is wrong: it's for a JTD engine... ).

Dreaded mcsf light kept randomly appearing, P0235 fault code, changed the boost pressure sensor, cleared it the other day. Still felt crap though reset the ecu tonight while I changed the oil n had dinner.

Totally different car now! Goes like a bullet!

156 1.8TS, 2002

Yep, this really works!

Followed the instructions to the letter, now the car is more responsive through all the revs and gears (2002 156 1.8 TS). And it also fixed my dodgy driver window which now goes up and down like a dream! Made me smile all day!

I have just carried out the ECU reset on my 2.4JTD 20v, and another 156 has been transformed. Well, perhaps thats a slight exaggeration but its a lot smoother and the MPG readout has gone up from a rather optimistic 48.5 ( actually 40 mpg) to a wildly optimistic 62.8 ! I presume MPG has improved and I will check next time I fill up to get a realistic figure.
So thanks Steve for the original post two years ago !

156 V6

Just done the ECU reset on my '99 156 2.5 V6 having replaced the MAF and the car now pulls like a train and is much smoother throughout the rev range but the idle is now very erratic and slow. Have tried the throttle reset on its own but this has made no difference. Any sugestions.

Wonderful Radio and central locking doesn't work! Going to look for other things now. Hope all is well after the 10 minutes!

NOT HAPPY!

All is well after leaving the car for 10 minutes or so the central locking worked first time although the radio took 15 mins or so to come to life.

Do you need to follow the guide down to the last second or is there a time scale to finish each step?

personallly engine should be allowed to reach temp where cooling fan comes on so engine has full temperature range

Thanks,

I did the reset the other day but wasn't sure if i missed a few seconds or left it too long etc.
I didn't notice any difference until i removed/installed the MAF. Seems smoother, could be placebo as the only reason i performed the reset was because i had it in me head the car felt a bit sluggish.

I had a leaky injector seal which has now been replaced.
However, when the car is cold and I lift off the accelerator pedal, it feels as though I've just hit the brakes.
The brakes are not sticking.
I was just wondering if the throttle reset would cure this?

Takes out knife and stabs you to death!

You are right though. Most of the "experts" now seem to be on 159 etc.

Did the reset earlier today, all is good and for the better, car feels more responsive, only hitch I had, fuel gauge light was dim for a few mins, but now back to normal.

Kept getting the VDC (ABS) error when I pressed the brakes, on my 147 2.0TS, a little too hard. I knew it wasnt a battery problem as the thing is brand new - so I searched around and found out about the faulty brake switch - took it out, gave it a bit of a clean and oiled the actual lever that srings in and out and what do you know the error hasn't seem to appear again for the last week or so. I then decided this morning that I was going to do a full ECU reset - just to see what all this talk was about. After the reset my power range lasts a lot longer in eacg gear (power on the throttle response only seems to dip after 6000 rpm ) acceleration is much smoother too. My idle is as flat as ever and sitting on 800 rpm (it used to jump around a bit and normally sit just above 1000 rpm) It feels like thing is brand new!!! Thanks guys out there this has been a definate win for me and my car!
