Has the check engine light come on? Also, have you checked the idle air control valve (IAC)? Also, make sure the EGR is working properly and not carboned.

Just a couple more things. Can you tell me the exact O2 sensor code you get? Also, have you checked the EGR and the MAF sensor? They most likely could use a good cleaning. NOTE: There is a special cleaner for the MAF. Make sure if you decide to clean it, you get it. Most parts stores will carry it. Also, the EGR (and intake where it mounts) could be carboned shut. Check that if you haven't and clean both making sure the EGR valve is working and sealing properly.
