1991 Buick Skylark 3.3L Poor Idle Quality, Hesitation, Misfire
Posted to GM Driveability on 3/15/2004 9 Replies

vehicle has a miss at idle and is most severe in gear brake on. the car runs great when driving down the road. i found a miss #2 cyl. and replaced the injector no help. it also has a slight stumble when you take off.
