Why do my spark plugs and coils keep going bad?
The leading cause of premature failure of an ignition coil is due to a worn or bad spark plug ignition cable. A bad spark plug ignition cable will have a much higher than normal resistance. This excessive voltage creates a high amount of heat which consequently melts the coil’s wire insulation.
What causes ignition coil damage?
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.
How do you know if your Honda Civic has a spark problem?
Take the engine spark plug wires, and plug them onto the end of the spark plug one at a time. Have an assistant crank the engine, while you watch the plug for a spark. You should see white light arcing between the electrodes of the plug. Make note of any wires that fail to deliver a spark to the plug.
What happens if you have a bad coil pack on a Honda Civic?
Bad Coil Packs are one of the more problematic ignition issues that can occur with the Honda Civic. A bad oil pack can make your Civic almost un-drivable. Or it may have little effect at all on the engine’s ability to run. It’ll get worse as they lose their ability to fire the spark plugs.
How do you fix a spark plug on a Honda Civic?
If the visual image of this is not clear, hold the spark plug at an angle from the grounding point (with the ground touching the threads of the spark plug), and the electrode free of any obstructions. Take the engine spark plug wires, and plug them onto the end of the spark plug one at a time.
What can cause a Honda Civic to misfire?
There is more to your Civic’s ignition system than just the coil packs. There’s also spark plugs and plug wires. There are also non ignition related circumstances that can cause a misfire. That would include lack of fuel pressure, bad fuel injectors, or even a timing chain (or belt) that has jumped.
