o2 sensor is part of regular maintenance that commonly gets overlooked (me too). I think they should be changed out ever 75k to 100k. I have 117k on mine, and its hasn't been changed.
I had a pretty rough idle and it ended up being my #5 plug. After I changed my plugs, it obviously ran a lot better.
It really depends on you and how rough your idle is. It wouldn't hurt to check your coil packs and possibly change out the o2 sensor. Good Luck!
