I had p0101, p0171, and p0174 codes for a week.. Tried everythign to fix it.. Ends up I overlooked a clamp on my intake that had somehow popped off and was letting air in the intake behind the MAF.. bank 1&2 were lean and got a mAF code. Fixed it and no code.. Had about 250 miles.. No damage cept maybe a little dirt sucked in it.
