My "check engine" light came on sometime ago. I have not noticed any loss of performance or gas mileage. What kind of problem could I have to cause he light to come on and stay on? I don't know if it is relevant, but I have changed the oli generally every 4000 to 5000 miles with synthetic oil of proper SAE viscosity.
