Question about 2002 Pontiac Grand Prix
Sounds like the catalytic converter is about ready to go bad. When the cat goes bad the car struggles to start, then when you try to acelerate its very slow. Start your car and have a friend rev the engine. Put your hand close to the tailpipe. I am willing to bet that not much pressure comes out when engine is reved up. I had mine replaced about a year ago. This sounds exactly like the same problem I had. The local pontioac dealer changed mine out for free. Check back I am interested in the results.
