Hey all!! My name is Tracy and i own a 99 grand prix gtp supercharged. Im having a rather major issue with it. It started out just randomly stalling and now it starts up, runs for about 5 seconds or so and cuts out. I've had the fuel filter, fuel pump and the fuel pressure regulator replaced and still nothing. It has been at the garage for about a week now and they are not finding anything wrong with it. Anybody have any ideas???
