Do I need to replace my o2 sensor??
Last week I replaced te pigtail plug on my alternator and I squeezed in the o2 sensor cable between the oil pan and driver side header and I forgot to move it, could it be that it melted the entire wire and now needs to be replaced? I didn't have time to check it out this afternoon but I will tommorow any clue on what my problem is??
im betting you might have disconnected the sesor somewhere or cut the wires either with the repair or when you were messing with the wires. take a look at those o2 sensor wires again. did you disconnect the sensor at all to reroute your wires?
