2. Use a spark plug socket and ratchet to remove the old spark plug.
3. Inspect the spark plug hole for debris and clean if necessary.
4. Install a new spark plug, ensuring proper gap (check the specifications in the owner's manual).
5. Tighten the spark plug to the manufacturer's torque specification (typically around 13 lb-ft).

3. Replace Ignition Coil

1. If the ignition coil shows signs of damage, replace it with a new one.
2. Install the new ignition coil by reversing the removal process.
3. Ensure the electrical connector is securely attached.

4. Clean or Replace Fuel Injector
