Are they oxygen sensor codes or are they lean codes. If you have P0171, or P0174 codes, they are not oxygen sensor codes. They are caused by a vacuum leak. If the leak is bad enough you should be able to hear a hissing noise while the engine is running. Otherwise the intake manifold gaskets are probably leaking. I would be happy to help further if you need additional info. Please post back.
