Solution

1. Preparation

Gather necessary tools and parts.
Tools Required:
- Socket set
- Torque wrench
- Feeler gauge
- Dielectric grease
Safety Warnings:
- Disconnect the battery before working on electrical systems.
- Allow the engine to cool before proceeding.

2. Remove Spark Plugs

Use the socket wrench to carefully unscrew each spark plug from the cylinder head.
Place the removed spark plugs in an organized manner to track which cylinder they came from.

3. Inspect and Clean

Inspect each spark plug for signs of wear, such as excessive deposits, burning, or cracks.
If they are dirty but still functional, clean them with a spark plug cleaner or wire brush.
Check the spark plug gap using a feeler gauge; adjust if necessary according to manufacturer specifications (typically around 0.030-0.035 inches for most models).

4. Install New or Reconditioned Spark Plugs

If replacing, install new spark plugs by hand to avoid cross-threading.
Tighten them to the manufacturer's specified torque value (usually around 13-15 ft-lb).
Apply a small amount of dielectric grease to the inside of the ignition coil connectors to prevent moisture intrusion.

5. Reassemble Components

Reinstall the ignition coils and ensure they are seated properly.
Reconnect the electrical connectors to the ignition coils.
Replace the engine cover if removed.
