Ignition Coil Video 

Your engine needs spark to run, and the ignition coil is the part that makes that spark possible. Its job is to take the low voltage from the battery and convert it into the much higher voltage needed to fire the spark plugs. Without that boost, the engine would never ignite the air and fuel mixture inside the cylinders.

When an ignition coil starts to fail, the engine may misfire, idle roughly, hesitate during acceleration, or lose power. A check engine light may also show up because one cylinder is no longer firing the way it should. Since spark is such a basic part of engine operation, even one weak coil can change how the whole vehicle feels.
