    I checked and they say o2 sensor lean bank 1 and 2. All I have done since is put a k&n filter in. Package said it was pre oiled so it wasnt me over oiling. Do I need to just take that filter off and clean MAF. Will electrical cleaner work or am I screwed and need a new MAF?

    I would try to reset the codes and clean your MAF. This is some good stuff.
