Hi I've gone through your post again and would like to ask you - if the LTFT and the STFT are of positive or negative values ? Lets say it´s only positive values you got from LTFT & STFT, then your are dealing with a lean condition, which by the way fits very well with the diagnostic trouble codes P...
