Seems likely it's the O2 sensor. If it's still not running great after the fix you could try plugs/wires/etc, cheap tune up parts.

I believe coolant damages O2 sensors, so if the you get the same code shortly after the fix, you may have a coolant leak in the engine. Just a thought, I'm not positive it that error would be caused by this.
