Relieve fuel pressure by removing the fuel pump fuse and running the engine until it stalls.
Disconnect fuel lines using a line wrench.
Remove the old fuel filter and replace it with a new one, ensuring proper orientation.
Reconnect the fuel lines and fuse.

4. Inspect and Replace Spark Plugs

Remove the ignition coil covers using a socket set.
Disconnect the ignition coils and remove them.
Use a spark plug socket to remove old spark plugs.
Inspect the spark plugs for wear; replace with new OEM plugs, torqued to manufacturer's specifications.
Reinstall ignition coils and covers.

5. Clean Throttle Body

Disconnect the throttle body electrical connector.
Remove the throttle body using a socket set.
Clean the throttle body with throttle body cleaner and a soft brush.
Reinstall the throttle body and reconnect the electrical connector.
