Spark plugs and ignition coils are key engine components that help to start your vehicle and keep it running. An ignition coil, also known as a trigger coil, is the induction system that converts the battery voltage into the electricity that stimulates the spark plugs. When the spark plugs are primed by the electricity from the ignition coils, they, in turn, spark the fuel to get the engine running. Without a charged battery connecting to a properly conducting ignition coil, the spark plugs won’t receive enough electricity to fire the fuel. Also, if the spark plugs are dirty or damaged, they won’t receive the charge and do their job. The ignition system that these components comprise is what makes your car start and keeps it running, so it’s essential that all the pieces are clean and working correctly. At San Antonio’s Best Mobile Mechanic, I understand the function and performance of this fundamental system, and it’s one of the things I can check and repair easily. When I perform routine maintenance on your car, I always ensure that your spark plugs and ignition coils are in good shape. I’ll make sure you never have to worry about your car starting due to a low battery or dirty or worn out engine parts. It’s a standard part of my inspection and tune-up.
