What causes ignition coils to keep going bad?
The top reason ignition coils fail is bad spark plugs or plug wires. Another potential cause is heat and vibration, which can damage the ignition coil’s windings and insulation. If an engine is experiencing repeated coil failures, the underlying cause may be resistance from worn spark plugs or excessive spark plug gap.
How do you know is a coil is bad?
Hard Starts. The ignition system needs to spark at the right time for the engine to ignite and the vehicle to run.
