Saturn SL2 133,000 miles “service engine soon” light is on?
My car runs good, is “service engine soon” light something to worry about? The light came on shortly after an accident. The car was idling rough for a while, but then it straightened up. I added Lucas Oil to the gas 7 or 8 times, started running smoother but light still comes on and goes off. I don’t have much money, any suggestions?
