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.
Do you have a scantool that can communicate with all of the modules on the car? I've never run into this code but Google said it has to do with the engine module losing communication with another or other modules. It would be helpful to know who isn't communicating.
