So I have a 98' TL Premium and for what ever reason the engine light comes on no matter what we do. It has been to the dealer several times and to several local shops and they both seem to agree that it's an exhaust sensor issue. But no one can seem to figure out how to fix it. They said that it was a sensor issue and replaced them all but with no luck. We also had them replace the computer for free, but that also hasn't seemed to fix the issue. Just wondering if anyone else has had that problem and what they did to fix it.

 

What kind of codes were detected?

 

how is the car running?? is it misfiring?? pull your spark plugs...see if they have oil on them.
