I have a 1995 16v turbo.

For quite a while now I have had an intermittent problem. When cold the engine will stall on idle, for example when stopping at traffic lights.

Also, it won't accelerate smoothly. It either stalls or bunnyhops. Sometimes I need 3000 revs just to move off. This is not fun.

After a few minutes of this, the idling revs start to oscillate up and down wildly between about 1500 and 500 revs. Sometimes it cuts out completely on the downswing in revs. After a while it smoothes out and the car is then normal.

Its fine after about 15 minutes of driving.

I have taken it twice to a garage. The first time they sold me a water temperature sensor. The second time they cleaned the idle valve, at my request. Neither has made any difference.

Any ideas?

Don't go to Fiat ........
I had exactlly the same problem with my Tipo 2.0 16v.... Turned out to be the Idle control valve, take it off and clean thoroughly with carb cleaner, Carbon deposits build up on the inside plunger and stop it working properly...

Already done this

Anyway I agree with 'pip' i'd check lambda sensor,done few of these recently.Also check plugs especially looking for oil in the 'tunnels' causing misfires.
