Could be the bank1 O2 sensor (driver's side front sensor B1S1), or you may have a rich condition on that bank. Possibly a leaky injector, or a leaky fuel pressure regulator. You can check the regulator by pulling the vacuum hose off of it and checking for the presence of fuel, if the end of the hose is damp or dripping with gas, the fp reg must be replaced. (fp reg is located in the middle of the driver's side fuel rail)

Not sure how rusted in your O2's are...but if they're not too bad you could always remove them and swap sides, then clear the code. If the same code comes up, you know it's not the O2 sensor, if the code comes up rich on bank2, you nailed it as a bad O2
