i have an 99 buick lesabre and the check engine light is flashing. when at a stop light or in idle the car kinda jumps or should i say feels like the engine is sputtering. then when i apply gas it like jumps harder til at a constant speed but it still feels heavy, is a bit louder and the light is still flashing. the car has approx 86000 mi. please give me some type of info on possible causes. i have been screwed over by 2 different shops previously on a different car and right now i have little or no trust for the mechanics in my area. at least with some ideas i can understand them more clearly and won't get taken for a ride. :(
