Solution

1. Preparation

Tools Required:
- Socket set (including spark plug socket)
- Torque wrench
- Ratchet
- Extension bar
- Gap gauge (if necessary)
Disconnect the negative battery terminal to prevent electrical accidents.
Ensure the engine is cool before starting the inspection.

2. Remove Spark Plugs

Locate Spark Plugs:
- Follow the ignition coil leads to find the spark plugs.
Remove Ignition Coils:
- Disconnect the electrical connector from each ignition coil.
- Unscrew the bolts holding the ignition coils in place and carefully pull them out.
Remove Spark Plugs:
- Using the spark plug socket, carefully unscrew and remove each spark plug.
- Take care to keep the order of the spark plugs noted for reinstallation.

3. Inspect Spark Plugs

Visual Inspection:
- Check for any signs of wear, such as cracks, carbon buildup, or oil fouling.
- Look at the electrode and insulator for any abnormal wear patterns.
Measure Spark Plug Gap:
- Use a gap gauge to ensure the spark plug gap is within manufacturer specifications (consult the owner’s manual for the correct gap).
- Adjust the gap if necessary by carefully bending the ground electrode.

4. Reinstallation

Install New or Inspected Spark Plugs:
- If replacing, use new spark plugs that meet manufacturer specifications.
- Carefully thread the spark plugs into their respective holes to avoid cross-threading.
Torque Specifications:
- Use a torque wrench to tighten the spark plugs to the manufacturer’s specified torque setting (usually found in the owner’s manual).
Reinstall Ignition Coils:
- Reinsert the ignition coils, securing them with the bolts and reconnecting the electrical connectors.

5. Final Steps

Reattach the engine cover if applicable.
Reconnect the negative battery terminal.
Start the engine to ensure smooth operation.
