Since the O2 sensors aren't that hard to take out, I'd give them a good cleaning. It can't hurt and may send a better reading to your computer. We do it quite a bit in our Ford shop. No kidding they really can effect your idle. I'm looking at one I just replaced. I wasn't able to clean it up enough to get it to work properly so I replaced it with a new one. Difference between night and day.

OH, ***** H CHRIST!! YOU CAN'T CLEAN THE O2 SENSORS!!! Use some common sense, people. :dunce: :sterb:
