U0100 Help
I’ve got a 13 Camaro SS A6 E38 PCM. Car just got cam, dod delete.
Car ran perfect yesterday during tuning. Went out today to work more on the tuning and when I started it, it was not idling well and had no throttle response. No MIL but I read codes and got a U0100 permanent.
Things I’ve done today,
Uploaded factory tune back in car, did not help.
Loosened and re-tightened 4 ground connectors on engine, did not help.
Un-plugged battery and un-plugged PCM connectors then put back, did not help.
Car will start, runs like crap, all the gauges work.
