Help with my Denali DTC codes.
So the check engine is on and I have tried clearing codes. They always come and go. I get P0101, P0137, and B0229.
I can't figure out whether the 137 code is being triggered by the 101 problem or vice versa. Could the 101 MAF problem be causing a code to trip from the 137 o2 sensor because the computer is adjusting the timing from a bad MAF reading? Doesn't the computer also compensate for the o2 readings?
Any ideas whether I should focus on the o2 sensor or MAF first? I replaced the intake system, and the code still keeps coming back. It did the same thing when stock as well.

There is an Other Cars Forum for this kind of thing!

Well it will never get answered here, and since this is pretty much a universal question as it would apply to any GM vehicle with the same issue I posted in tech. I will just start replacing stuff, the question will never get answered here.
