Message	Okay so the car was at the body shop for 2 days and just as i was about the go home Z wouldn't want to start.. I tried depressing the gas pedal several times while starting, car still didn't start.. so i ran the ecu codes and ecu threw code 21.. I had an S2 PTU home so i went back home with a friend and got that PTU to replace my S1 PTU.. After i installed the S2 PTU, ECU gave code 55 however car didnt want to start just as before.. it took around 10 min to start the car and the moment it did, it started backfiring alot and i mean ALOT.. after around 5min of rough idling the Z got normal and i took a spirited drive back home with the car acting perfect.. The question here is all this trouble starting after i installed the S2 PTU and the backfires and rough idling for 5 min were due to excess fuel?
