i unplugged the oxygen sensor, let it warm up, and then took it on a drive to alburtsons, not a long drive but a few miles and enough that the light would have normally come on. it did not come on at all.
does this mean the o2 sensor is bad? the only difference in the drive was the idle did not always drop down as low.
