try fixing your 02 sensor first. Most people fix it, and this code will go away. I have this problem, and the 02 sensor unfortunately was not the culprit for me, but hopefully for you that is all it is.

Check Gas cap (for pressure seal), gas pump, gas filter, clogged injectors, running on low fuel level? Over advanced ingnition? Octane too high? Spark plug temp out of range?
