Remove the spark plug wires gently using a spark plug socket.
Inspect each spark plug; replace if necessary (gap to manufacturer specifications).
Reinstall the spark plugs and reconnect the wires securely.

4. Clean Throttle Body

Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft cloth to clean the inside of the throttle body.
