Why does my check engine light keep going on after replacing the oxygen sensors?
I have had my car in for repair 3x in 2012 to have oxygen sensors and the EGR valve replaced. But the check engine light keeps going on. I am waiting for the traction control off light to go on soon, as well. The mechanic is scratching his head. Can someone help?
Get the codes read and write down the numbers. I imagine the mechanic has done that in between bouts of head scratching.
