I only have a simple OBD2 app that cannot export. I'm getting the cable now so i can run INPA.
STFT: +-3 on bank 1 - Idle
STFT: +-4 on bank 2 - Idle
STFT: +15 on bank 1 - 2500RPM
STFT: +22 on bank 2 - 2500RPM
On load, STFT will go up and LTFT will come down.

I had same problem on both both like you. Mine was defective DME although you wouldn't think it was...10K in parts and 2 year later I fixed it. Injector first then DME. This is not an air leak. Post a log as it will help. If you LTFT are very transient and look more like a O2 sensor log then it most likely the DME
