Solution

1. Preparation

Gather necessary tools and parts: spark plug socket (usually 5/8 inch), ratchet, extension bar, torque wrench, and a gap gauge.
Ensure the engine is cool before starting the procedure to avoid burns.

2. Remove Spark Plugs

Step 1: Disconnect the ignition coil connector from the spark plug to access the spark plug.
Step 2: Remove the ignition coil by unscrewing the bolts using a socket wrench.
Step 3: Carefully pull the ignition coil out of the spark plug hole.
Step 4: Place the spark plug socket onto the spark plug, ensuring it fits snugly, and use the ratchet to turn it counterclockwise to remove the spark plug.

3. Inspect Spark Plugs

Step 1: Examine the spark plug for wear, carbon deposits, or oil fouling.
Step 2: Measure the gap between the electrodes using a gap gauge; refer to the manufacturer specifications for the correct gap measurement.
Step 3: If necessary, clean the spark plug using a wire brush or replace it if damaged.

4. Install Spark Plugs

Step 1: Apply anti-seize compound to the threads of the new spark plug (if applicable).
Step 2: Insert the new or cleaned spark plug into the spark plug hole and hand-tighten it.
Step 3: Use the ratchet with the spark plug socket to tighten the spark plug to the manufacturer's recommended torque specification (usually around 13-15 ft-lbs).
Step 4: Reinstall the ignition coil and reconnect the ignition coil connector.

5. Reassemble Engine

Step 1: Replace the engine cover and secure it with the appropriate fasteners.
Step 2: Reconnect the negative battery terminal.
