I'm new on these forums, and am posting on behalf of a female friend of mine with a 96 RS. Her car is completely stock and runs great, however, whenever she turns on the A/C her car will begin to stutter and jerk. This occurs mainly while she's not moving and disappears when the AC is turned off. Upon movement, the stutter is less noticable. I don't believe it effects her RPM's so I'm not led to believe her IAC is the cause. Could it possibly be a mis-aligned AC pully causing the car to rock?
