Solution

1. Preparation

Tools Required: Socket set, torque wrench, ratchet, extension, spark plug socket, feeler gauge, anti-seize compound.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the engine to cool completely before starting.

2. Remove Components

Sub-steps:
1. If equipped, remove the engine cover by unscrewing any bolts or clips.
2. Detach the spark plug wires or ignition coils by carefully pulling them off the spark plugs. Label them if necessary to ensure proper reinstallation.
3. Use the spark plug socket with the ratchet and extension to remove each spark plug by turning it counterclockwise.

3. Inspect and Clean

Sub-steps:
1. Inspect the removed spark plugs for signs of wear, including carbon deposits or damage.
2. Clean the spark plug holes with compressed air to remove debris.
3. Check the spark plug gap using a feeler gauge; adjust if necessary according to the manufacturer's specifications.

4. Install New Spark Plugs

Sub-steps:
1. Apply a small amount of anti-seize compound to the threads of the new spark plugs.
2. Carefully thread the new spark plugs into the holes by hand to avoid cross-threading.
3. Tighten the spark plugs using a torque wrench to the manufacturer's specified torque (typically around 13-16 lb-ft for Toyota engines).

5. Reassemble Components

Sub-steps:
1. Reinstall the ignition coils or spark plug wires, ensuring they are seated securely.
2. Reattach the engine cover if it was removed.
3. Reconnect the negative battery terminal.
