Re: Missfire Returned 01 Gt

Don't give up. These type problems can be resolved. Since you've ruled out the CAT and other possibilities I suggest checking out the fuel injectors. Maybe one or more is dirty/clogged or defective. These can de done DIY or just have a mechanic that has the proper fixture to do fuel injector cleaning service.

On the ground, it would be a good idea to check it at the engine/tranny grounding stud.

Other possibilities would be the ignition control module (ICM) and even the coil packs. Coil packs can be swapped out with each other.

Is it a random misfire code P0300 or code consistent with a specific cylinder such as P0301 - P0306?
