Hmmm frustrating problem...

1- there is an idling problem with my car. it decreases to 500 rpm and suddenly increase to 1200. you can alsa see it's video at this link below >>

alfa romeo Idle problemm - YouTube

2-and also car's traction decreased at ramps...

3-when I start the air conditioner, idle problem show itself more...sometimes car stops when I start air conditioner.


1-I guess it can be the "idle control valve" >> it is shape is below

2- Maybe MAF sensor. But I changed it with it is new one. And problem not changed.

3- Thorttle body. I cleaned it with it is sprey. Problem goes on.

4- I am using open air filter. But I dont think that it will cause this problem.

I would say the same, sounds like an air leak.

Crankcase breather pipes and idle breather valves... is it a fly by wire or cable throttle?
