Ignition coils are the unsung hero of the engine. Spark plugs get all the glory of providing the spark to ignite combustion, but it’s the ignition coil that provides the electricity to the spark plug. The coil draws a voltage from the 12V battery, amplifies it, and sends it through to the spark plug. Just as knowing when your spark plugs are failing is important, it’s equally important to be aware of the signs of a faulty ignition coil.
A faulty coil could cause major performance and structural issues for your vehicle, so if you suspect you may have faulty coils—or are experiencing any of the below symptoms—visit your local AAMCO Colorado Location to have an expert mechanic take a look.
