We have the most modern equipment and resources to diagnose the onboard computer diagnostic system (OBDII) equipped in your vehicle. OBDII monitors can detect anything from a loose fuel cap to a spark plug misfire. An illuminated check engine light means that you should have your vehicle checked as soon as possible; a flashing check engine light means that you should park and shut off the vehicle immediately before engine or emission system damage occurs. If your check engine light comes on, please stop by so we can repair your vehicle quickly and at a great price.
