Download Article Show Download Article The ignition coils in your engine produce an electrical current that’s carried through your ignition cables (spark plug wires) to the spark plug. That current then flows through the plug to detonate the air and fuel mixture inside the cylinder. A faulty ignition coil can result in a misfire or even the engine failing to run.[1] Once you’ve identified which coil is causing the issue, you can test the ignition coil to be sure it’s the problem. Replacing a bad coil can be done in just a few hours with common hand tools.
