What causes an o2 sensor to go out? I have hooker longtubes on my car. I have to stock 46k mile o2 sensor in the passenger side header. But on the driver side its been through at least 4. I had a new one put in yesterday and the codes cleared and today the ses light came back on. They put a tech 2 scanner on it and the passanger side was fluxuating between 400-600 (if i remember correctly) but the driver side started at about 100 then dropped to 0-4 then we took it for a ride and it started to operate in a normal range. Why do I have to keep putting o2 sensors on the driver side but the passenger side is the original one that came with the car. There are also o2 extenders on the car so the wires aren't cut and spliced. The headers are also uncoated.
