What Causes Ignition Coils To Keep Going Bad? Ignition coils can go bad due to problems with the spark plug and plug wires, an abnormal spark plug gap, extra moisture around the coil, overheating, and excessive vibrations.
What would cause an ignition coil to fail?
Coils fail for a variety of reasons including heat, vibration, or issues on the secondary side of the ignition system. Worn secondary ignition components such as spark plugs or wires can cause a coil work harder, require more voltage, and therefore significantly reduce the operating life of the coil.

Do aftermarket ignition coils make a difference?
A high performance ignition coil helps engine performance four important ways. First, the higher voltage allows for a larger spark plug gap, which results in a more robust initial flame kernal at the start of combustion. The result is a real-world engine torque increase.
Can a bad ignition coil cause transmission problems?
It's possible that a bad coil in itself could cause the car to jerk when shifting into gear, but any misfire bad enough to cause this kind of jerking will probably manifest as a noticeable engine shaking under other conditions as well.
