Solution
1. Preparation
  • Gather tools and components:
    • Tools: Socket set, torque wrench, spark plug socket, multimeter, feeler gauge.
    • Parts: Replacement spark plugs (if necessary).
  • Ensure the vehicle is parked on a flat surface and the engine is cool.
2. Remove Spark Plugs
  1. Disconnect the negative battery terminal to prevent electrical shorts.
  2. Remove the engine cover (if applicable) by unscrewing the necessary bolts.
  3. Carefully disconnect the ignition coil connectors from each spark plug.
  4. Use the spark plug socket to unscrew and remove each spark plug from the cylinder head. Keep them in order to ensure proper reinstallation.
3. Inspect Spark Plugs
  1. Examine the spark plugs for signs of wear, such as fouling, cracks, or excessive carbon buildup.
  2. Measure the spark plug gap using a feeler gauge; refer to the vehicle's service manual for the correct gap specification.
  3. Check the resistance of each spark plug using a multimeter; it should typically be between 4,000 and 6,000 ohms.
4. Install New Spark Plugs (if necessary)
  1. If the spark plugs are worn or defective, install new ones:
    • Apply a small amount of anti-seize compound to the threads of the new spark plugs (if recommended).
    • Insert the new spark plugs into the cylinder head and tighten them by hand.
    • Use a torque wrench to tighten to the manufacturer's specified torque (check the service manual for exact values).
  2. Reconnect the ignition coils and ensure the connectors are secure.
5. Finalize Installation
  1. Reinstall the engine cover (if applicable) and secure it with bolts.
  2. Reconnect the negative battery terminal.
  3. Clear any diagnostic trouble codes using the OBD-II scanner.
