    The Oxy light came on the other day. The car runs and drives fine. I read that when the sensor goes bad the car will run rough but so far I have not encountered that. I also read that there is a switch behind the gauge cluster that needs to be reset every 30,000 miles. I took the dash apart and found no switch. Does anyone have any ideas or experience with this? Thanks
