1991 Pontiac Grand Prix STE 3.4L Poor Idle Quality, Hesitation, Surge, Stall
Posted to GM Driveability on 8/11/2003 9 Replies

car surges at idle and has a constant miss at idle and cruising speeds. at 30 mph in 3rd gear it will start to surge and jerk until the throttle is released. car dies after idling a few minutes hot but will always restart.
