I have an intermittent miss fire on my 03 Grand Am GT 3200cc engine. It happens between 60 and 70 Km hr and 80 and 90 Km hr. And it does not happen all the time, only when I step on the gas. This has just started happening. I have a feeling that it could be dirt in the tank. I think this because when I fill the tank no miss fire, let it sit and it starts again. Any ideas? Oh yes I put my code reader on the car and I do not get any codes.
