Hello....
Can anyone give me adivse on how to clean the ISV, don't you take the screw out and leave it in CARB cleaner all night, i'm not sure how to do this.
My car is a 1989 GTI 16v 1.8
When slowing down to juntions and putting the clutch in the car wants to stall then the rev's get them selved back to normal until i stop again.
Any advice would be great....
cheers lads.
