An ignition coil is a high voltage transformer in your ignition system which transforms the battery's low voltage to the thousands of volts needed by the spark plugs to start your engine and keep it running smoothly. If your ignition coil is not working properly, it will not be able to create the spark to ignite the air & fuel mixture, causing a backfire or misfire. A bad ignition coil can severely damage the catalytic converter or engine. If you're experiencing a misfire, backfire, or other issues, have Q3 Car and Truck Repair - Capitol Heights in Capitol Heights and Waldorf Areas, MD, perform a diagnostic service. You can call Q3 Car and Truck Repair - Capitol Heights at 888-320-0766, or schedule an appointment online.
