gr8gatzby Posted September 19, 2005 Report Share Posted September 19, 2005 CEL came on today when I reached Boone, NC and remained on throughout my mountain drive down the blue ridge parkway. On the way back home it remained on when reaching the lower altitude...until i turned the car off. When i cranked her back up the CEL was gone. The car did great all day, CEL on or off, I could tell no difference. Link to comment Share on other sites More sharing options...

The car did great all day, CEL on or off, I could tell no difference.Pull codes than.From personel experiance, I have had an intermittant CEL of late that is from the front O2 sensor [codes PO133 and PO135, front o2 sensor slow response and front o2 heater circuit fault]. No difference in performance whether CEL is on or off [just crappy gas mileage in town- freeway is fine] Link to comment Share on other sites More sharing options...
