Replace Acura Ignition Coil
Is your vehicle misfiring, having a rough idle, dying at idle, or is the engine shaking? Learn how to fix it by simply replacing the Ignition Coil.
Changing the ignition coil on Acura vehicles is not as difficult as you think. The four-cylinder Acura engine is easy to work on, and you can change the ignition coils yourself in less than an hour. The 3.5L V6 Acura engine requires slightly more time.

Procedure
Park the ACURA on level ground. Allow the engine to cool down before replacing the ignition coils to avoid getting burned.
Pull the hood release located under the dashboard (driver’s side). Open the hood.
Disconnect the negative battery terminal. You need to disconnect the black cable with the (-).
Remove the engine cover.
In most ACURA, the engine cover can be removed simply by pulling it up. If you see bolts on top of the engine cover, remove them.
Unplug the electrical connector from the ignition coil. Press the small tab, then pull. Repeat this step for all coils.
Remove the 10mm bolts that secure the ignition coil in place.
Remove the ignition coil from the engine block. It may be difficult to pull out the coil. If that is the case, try twisting the coil as you pull it out.
Install new ignition coils on your ACURA engine. It is recommended to apply dielectric grease to the boot whenever possible.
Reinstall the engine cover. Connect the negative terminal and start the car.

Changing all Acura coils at the local Acura dealer or auto repair shop costs anywhere from $400 to $600. This job typically costs about $100-$150, sometimes even less.
While you can change just the defective coil, it is recommended to change all coils at once. If you are on a tight budget, you can replace only the bad coil, but remember that another coil may fail a few months later.
Check Engine Light Still On
If the check engine light is still on after you replace the Ignition Coil, you can use the YOUCANIC Full System Scanner to clear the stored codes. This scanner can also read and clear fault codes on every control module of your Acura vehicle.
