Solution

1. Preparation

Gather tools: Spark plug socket, ratchet, torque wrench, feeler gauge, OBD-II scanner.
Ensure the engine is cool to avoid burns. Disconnect the battery to prevent electrical shorts.

2. Remove Components

Remove the engine cover if applicable using a socket set.
Disconnect any electrical connectors from the ignition coils.

3. Remove Spark Plugs

Use a spark plug socket to carefully unscrew and remove each spark plug from the engine.
Inspect each plug as it is removed for signs of wear or damage, such as excessive carbon buildup or corrosion.

4. Inspect and Clean

Use a wire brush or spark plug cleaner to clean any debris from the spark plugs if they are to be reused.
Measure the gap of each spark plug with a feeler gauge; adjust or replace if necessary.

5. Install New or Cleaned Spark Plugs

If replacing, install new spark plugs by hand to avoid cross-threading.
Use a torque wrench to tighten them to the manufacturer's specification (typically around 13-18 lb-ft for Honda vehicles).
Reconnect the ignition coils and any electrical connectors.

6. Reassemble

Replace the engine cover if removed.
Reconnect the battery terminals.
