P0101 mass or volume air flow A circuit range/performance
P0172 system too rich
90K miles has GMPP stage 2 kit and stage 2 tune as far as I can tell
the STFT and LTFT spend most of the time -10% or more
MAF sensor bad? or is the MAF table that far off?
this is the first time messing with one of these. I have no problem doing a tune if needed.
I only has a few minutes to mess with it so far and didn't set up the scanner as well as I should have hopefully the log is good enough for now.
base 6-6-14.hpt
log 2.hpl
