I look up these codes and they are System Too Lean on Bank 1 and Bank 2. What do I do to fix these?

Hi Cbuss,
It means fuel supplied is too low.
Either you have a fuel pressure problem or the fuel filter is clogged. Try replacing the fuel filter first.

Could it be the O2 sensors?

Hi Cbuss,
Yes, if the O2 sensors are out, it could give you the code also.
