I seem to get a vibration on 2 things, 1.... Pretty bad when the fans cut on in the car, the RPM's drop and the car ideals low and vibrates because of it, and 2.... When im turning the wheels while either at a stand still or at a slow role. I was wondering if it may have something to do with the belt system, maybe a belt is to tight, cause I know iv had to adjust it a few times because it was replaced not to long ago because of wear and was a squeaky son bastard lol. Just wondering if any of you guys either have this problem or had it and did something and what you did about it.
