Question about 2002 Pontiac Grand Prix
As I said in another post, check the catalytic converter. That fixed my problem!

Need to check you exhaust system for leaks. You can easily do this by getting the car up on jack stands and use the backside of your hand holding it close BUT NOT TOUCHING OBVIOUSLY to find the leak.
Engines need backpressure which is essential for the effeciency of the engine.
