I went WOT in 2nd and right around 4-5krpm my car bucked and immediately had a flashing CEL and my car was running rough with lost power.
The CEL would stop flashing at some points, but would come back again a few minutes later. Car continued to run like crap no matter what.
I know P0301 = Cylinder 1 Misfire But I also had a ?????? code.
Any suggestions what it could be? From what I found out myself, it could be the plugs or the coil pack.
