Remove the intake duct attached to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate.
Ensure the throttle body is free of carbon buildup.
Reattach the intake duct and secure it properly.

4. Check and Replace Spark Plugs

Remove the ignition coil(s) from the spark plug hole using a socket wrench.
Extract the spark plugs using a spark plug socket.
Inspect the condition of the spark plugs; replace if worn or fouled.
Reinstall new or cleaned spark plugs and reattach the ignition coil(s).
