Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent electrical shorts.

2. Remove Ignition Coil

Locate the ignition coil on the engine block.
Disconnect the electrical connector from the ignition coil by pressing the release tab.
Remove the mounting bolts securing the ignition coil using a socket set.
Carefully pull the ignition coil out of the spark plug well.

3. Inspect and Test

Inspect the removed ignition coil for physical damage.
Test the ignition coil's primary and secondary resistance using a multimeter. Compare results with manufacturer specifications.
If testing indicates a fault, proceed to replace the ignition coil.

4. Install New Ignition Coil

Take the new ignition coil and apply a small amount of dielectric grease to the connector end.
Insert the new ignition coil into the spark plug well, ensuring it seats properly.
Reinstall the mounting bolts and tighten them to the manufacturer's specified torque.
Connect the electrical connector until it clicks into place.

5. Reconnect Battery and Test

Reconnect the vehicle's battery terminals.
Start the engine and check for normal operation.
Monitor for any warning lights or symptoms of misfiring.
