Are there any trouble codes in the engine DME?

What are the hot idle adaptations:
  • Short term fuel trim bank 1 %
  • Long term fuel trim bank 1 %
  • Short term fuel trim bank 2 %
  • Long term fuel trim bank 2 %
  • RPM
  • MAF flow in g/s

It sounds like your codes are for "misfire with fuel cut off". In other words, the cylinder is misfiring so often that the DME has cut the fuel off of that cylinder to stop damage from occurring. It resets after turning the engine of and back on again.

The 99% values are for the O2 sensor heater systems and that's good values.

The Multiplikative values of 12% is too high. It's indicative of a vacuum leak or a failing fuel pump. Both require the DME to add extra fuel.

Follow the misfire guide linked in post #4
