I have a 2003 Bonneville SE and it is running really rich. See mod list below. It doesn't seem to matter if I have my ZZP pcm in or my stocker, I pretty much get the same results. I put my stocker in Sunday and it seemed to get better for a while and slowly started to get rich again. Anyone have any ideas?
The powertuner I am using is set up for a 1998 grand prix and won't read my pcm. I am able to use the scantool but I have very limited features to view. I have LTFT, STFT, MPH, FT CELL, AND IPW and that'* about it. I will see if I can post the scan for you.
