Locate the spark plugs using the vehicle's service manual for specific locations.
Disconnect the ignition coils from the plugs.
Use a spark plug socket to remove old spark plugs.
Inspect the plugs for wear and gap specifications.
Install new spark plugs, ensuring the proper torque (typically 12-15 lb-ft).
Reconnect the ignition coils.

4. Inspect and Clean Fuel Injectors

Remove the fuel rail assembly as per the service manual.
Disconnect the fuel lines and electrical connectors.
Clean the fuel injectors with a fuel injector cleaning kit or replace them if faulty.
