I had my car parked for 4 years and did a few things to my car while it was parked, but I am still dealing with WOT sputtering. It sputters as if I have ****ty gas or the spark plugs are garbage. Both are not the issue and I tried to eliminate the standard things that would cause this: clean MAF, throttle body, installed Pacesetter headers, 3" deleted cat exhaust, ZZP PCM, deleted rear o2, new front o2, new fuel pump, fuel filter, and it goes on..
Does anyone have ideas? No codes other than a new EVAP code that is probably my gas cap.
