Installed CT header, and when switching the o2 over, I think it got damaged. Started throwing "Front Bank o2 Heater Circuit" so swapped it out for another o2. Replacement shows more resistance that the first, but it wasnt at room temp when testing, but Im assuming thats not the problem. Any idea where to start looking? Going to have to trace all the wires back is what its looking like. Is this common for the '04? (Like most of the problems lol) Thanks for any help.
