1990 Buick Riviera ProblemsABS accumulater may fail
The anti-lock brake (ABS) accumulator may fail causing loss of power brake assist. (The brake pedal will become very hard.)
Problems with anti-theft systems using the raised-chip key can prevent the car from starting. The wires in the steering column to the ignition lock cylinder tend to break. The key and ignition lock cylinder should be replaced to correct this condition.

Question - how do I re-adjust the door hinges after replacing the hinge pins? I had to back off the hinge bolts in order to replace the hinge pins but when I tighten t he bolts, the door is way out of alignment. I cant find any site online that can give me advice on this.
