Locate the air filter housing and remove it using a screwdriver.
Take out the old air filter and inspect it for dirt and damage.
Install a new air filter, ensuring it fits securely.
Reassemble the air filter housing.

3. Inspect and Replace Spark Plugs

Remove the ignition coil cover (if applicable) using a socket set.
Carefully disconnect the ignition coils and remove the old spark plugs using a spark plug socket.
Inspect the spark plugs for wear; replace them with new plugs of the specified type.
Reinstall the ignition coils and cover.

4. Clean Throttle Body

Locate the throttle body and remove the intake duct using a socket set.
Use throttle body cleaner and a soft brush to clean the throttle plate and housing.
Reassemble the intake duct securely.
