What are the signs of a bad ignition coil?
Ignition Coil Problems, Symptoms and Solutions
- Engine misfires.
- Rough idle.
- A decrease in car power, especially in acceleration.
- Poor fuel economy.
- Difficulty starting the engine.
- Check engine light is on.
- Exhaust backfiring.
- Increased hydrocarbon emissions.
How hard is it to change an ignition coil?
A faulty ignition coil can result in a misfire or even the engine failing to run. 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.
Is it OK to drive with a bad ignition coil?
It is possible to drive with a faulty Coil On Plug (COP), but not advisable. Driving with a faulty waste spark ignition system won’t be possible. Driving with a faulty coil pack can damage other components of the engine.
What will cause an ignition coil to fail?
Excessive heat and vibration can cause the insulating material to break down and create internal coil failure. 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.
Should you change ignition coils when changing spark plugs?
Whenever you change spark plugs, it is a good idea to replace the ignition wires and vice versa.
