Solution

1. Preparation

Tools Required: Socket set, torque wrench, feeler gauge, spark plug gap tool.
Disconnect the negative battery terminal to avoid electrical shock.
Allow the engine to cool completely before starting work.

2. Remove Spark Plugs

Sub-steps:
1. Remove any engine covers that may obstruct access to the spark plugs.
2. Carefully disconnect the ignition coil or spark plug wire from each spark plug, noting the order for reinstallation.
3. Using a socket wrench, unscrew the spark plugs from the cylinder head.
4. Place the removed spark plugs in order to keep track of their positions.

3. Inspect Spark Plugs

Sub-steps:
1. Check the condition of each spark plug for signs of wear, such as cracks, corrosion, or excessive carbon deposits.
2. Measure the gap between the electrodes with a feeler gauge and compare it to the specifications provided in the service manual.
3. Clean any deposits using a wire brush if the plugs are reusable.

4. Replace or Reinstall

Sub-steps:
1. If the spark plugs are worn or damaged, replace them with new ones of the same specifications.
2. Apply anti-seize compound to the threads of the new spark plugs (if required).
3. Install each spark plug by hand to avoid cross-threading, then tighten with a torque wrench to the specified torque values.
4. Reconnect the ignition coils or spark plug wires.

5. Reassemble and Test

Sub-steps:
1. Replace any engine covers removed during the process.
2. Reconnect the negative battery terminal.
3. Start the engine and listen for smooth operation, ensuring there are no misfires.
