So I just got my car back a few weeks ago and it drives great and pulls nice and hard. My only issue is that when I press the clutch in my idle will tend to jump about 200rpm up and down also if I throw the car into neutral while rolling up to a stop sign the idle will jump and that is without anything pressed in. Usually when I finally stop at the sign the idle will still jump about 3 times then stop. The only thing that really got changed on the car was the IACV and turbos replaced. Not sure what it could be cause everything seems find under the hood. I think it's an electrical issue. Any other suggestions?
