1991 Pontiac Grand Prix GT 3.4L Stall
Posted to GM Driveability on 10/5/1998

Intermittent stalling at idle. Problem happens so fast that any attempts to record data is not helpful. Vehicle will restart immediatly. Has the latest prom update. No other problems found. Seems to be a ECU power loss if we had to make a guess.
