Ok, 2001 Gt Auto, I`ve got a new fuel filter and tranny filter on the way, along with a haynes manual. Anyways the other day, it started missing, and seems like its getting a little worse. Seems like it gets worse as it warms up, but could just be me. 67k on the car, best places to start looking? I ordered a code reader this morning for it, because it popped on a service engine soon light, and of course half way through the day, the light goes out. Still missing though. Thanks guys.
