I had the O2 sensor replaced, and the "check engine" light was off for a few days, then it came back on. The O2 sensor was replaced again. The "check engine" light came on after about 6 hours.
Any idea what would cause O2 sensors to fail so quickly - or is there some other problem?
have the same problem?
