the o2 sensor must be replaced....you can clean other sensors however...i know the MAF can be cleaned...don't worry too much about o2 sensors...well, it depends on which one goes bad....if your secondary one is bad, don't worry cuz it won't effect anything except throw an annoying SES....if your primary goes bad, it will revert to secondary as back up...so your good to go there...however, if your secondary is bad as well, then your gas mileage will suck...
