Message	I have a 1992 300zx and it is misfiring on the back two cylinders. This happened randomly at start up one day. I have tried everything from switching coils and spark plugs to testing the injectors. I am getting power to the two fat wires going to the coils and power to the injectors too. I pulled the plugs and they are wet. Does anybody have any idea why I'm still misfiring? I have tried EVERYTHING! I have codes 21, 34 and 51. I think the 21 appeared from me unplugging the coils while the engine is on.
