I have the lean codes again. Both banks. I was on the way to a friends apartment and it went on.
P0174 and P0171
I've gone through this for the 'n'th time now. I've replaced egr gasket, IAC, and IAC gasket, The TB gasket, All the clamps were redone. New plugs are in and have been running find for about 2 months. I have no clue on how I keep getting lean codes in both banks. Is it at all possible that both O2s are bad?
