I'm not sure about the age of my O2 sensor. Older than 60k I think but I don't know after that. Lifespan is 80k I think, and the owner then did most required maintence from what I can tell so it might still be good but I don't know.
The engine ran rich for a while, does this foul the O2 sensor like it does the spark plugs? Definitely going to replace if so.
