replaced mass air flow sensor a week ago. light came back on with these codes again. says the fuel system for bank 2 was too lean. for a guy who doesnt know much about vehicles, what is this saying? ive read in other posts about vacuum leaks and my intake mannifold. is this what im lookin at? i just dont want to replace oxygen sensors if its as commonly misdiagnosed as im reading. thanks in advance for any help i can get.
