I'm getting CODES P0171 to lean bank one
and P1133 something O2 sensors with bank one?
Anyone think that I need a new O2 sensor?
If you get two codes for bank one sensor one I would try a new O2 sensor . If it does not fix problem the only other thing is to check fuel pressure, and injector pulse. But more the likely it is O2 sensor I been through several myself
