Radiator repair and much more
Auto parts employees are qualified only to interpret the trouble codes, not to diagnose and repair. Go to a certified technician if you want service done right. Minor issues like a loose gas cap, bad spark plug wires or moisture in the engine can trigger a check engine light. If your light indicates a non emergency, first check your gas cap and then your engine for wetness before taking your car in for repairs. Engines will misfire if spark plug wires wear down; give them a look as well.
