chugs down the road, stalls at low idle.

Asked by Apr 14, 2013 at 02:23 PM about the 1998 Pontiac Grand Prix 4 Dr GTP Supercharged Sedan

Question type: Maintenance & Repair

have replaced fuel filter, O2 sensor, alternator and belts, recently fixed supercharge. Some days runs just fine, other times it chugs, like its not getting gas. Usually this chugging lasts just a few seconds, however, now it stalls in idle, at stop signs; even when on cruise control at 70mph. very frustrating, keep fixing, something else falls apart.
