Question about 1998 Cadillac Seville
I found the codes for my cadillac seville that my oxygen sensors are telling me which ones are bad. Question is are they the front or the back ones, they are P0171 System to lean (bank 1)(2) and P0174 System too lean (bank 2). can anyone help with the codes, any advise will help me. Thanks David
Oxygen sensors are fine you have a air leak check intake for leaks start with checking all inlet pipes rubber hoses if ok check fuel press if ok most likely mass air flow sensor i am leaning toward air leak.
