What Is Ignition Coils？
The ignition coil provides the necessary high voltage and ignition energy for producing high voltage sparks at the spark plug.
Bad Ignition Coil Symptoms
When your coil starts to fail, your first sign is probably a "check engine" light and a misfire trouble code for a cylinder. Since ignition coils supply power to the spark plugs, a faulty coil can cause symptoms that may seem spark-plug related, so have the code read to narrow down the issue.
If you are just getting a general misfire code, it's worth a shot to replace the plugs first if they are due, as a full set is very affordable maintenance.
If your issue is not the spark plugs and you ignore the "check engine" light, the coil will further degrade, causing engine misfires, rough idling, and poor acceleration.
You may also notice the vehicle is harder to start. If it gets really worn out, you may start noticing backfires or rough bucking and jerking while accelerating. Don't keep driving it, as the symptoms won't go away, and you'll be putting stress on other engine components. An ignition-related misfire, for instance, would mean fuel is getting into the exhaust and would destroy a catalytic converter.
How to Replace an Ignition Coils?
What You'll Need
- New ignition coils
- Ratchet & Socket set
- Dielectric grease
- Gloves
- Repair manual
Step
1. Remove the negative battery cable.
2. Locate coil packs or ignition coil in the engine bay. If your car has a distributor, follow the wire that is in the center of the distributor cap to find the igniton coil. Cars with coil packs usually have them mounted near a valve cover. Coil on plug ignition coils are typically placed near or directly over each spark plug. Remove any plastic engine covers or air intake tubes to gain access to the coils.
3. Unplug the wiring harness by pushing the tab and pulling off the electrical connector.
4. Remove the retaining bolts holding the coil in place. Once unbolted, the coil pack can be easily pulled out of the engine now, but be aware that some models have a locking tab that needs to be opened.
PRO TIP：If you have a coil pack, label the spark plug cables with masking tape and assign each a number. Once the replacement coil is in place, you can correctly reattach all the cables. If you have room, you can also remove the spark plug wires and attach one at a time to the new coil pack. Once all wires have been transferred, you can unbolt the old coil pack and install the new.
5. If it is time to change the spark plugs, do that now.
6. Apply dielectric grease inside the end of the coil-on-plug style, as this prevents the boot from sticking to the spark plug and helps keep water out of the connection.
7. Slide the coil into place, pressing firmly so the boot clicks onto the spark plug. Reattach the electrical connection and the coil pack retaining bolt.
Proceed to the next coil pack until all units have been replaced. Finally, reconnect the negative battery cable.
