My 10 t and c was misfiring cylinder 1. I ordered these ac Delco plugs and ignition coils and fuel injectors. 6 of each. I removed champion plugs. They were pretty beat up . The new delcos are firing nicely. You have to remove the upper intake to do this project. For the price I chose to replace all possible problem parts at the same time since it was under 200 for everything.
