Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to prevent electrical shorts.
Ensure the vehicle is on a level surface and secured with wheel chocks.

2. Inspect and Clean the Throttle Body

Remove the air intake duct connected to the throttle body using a socket set.
Clean the throttle body with throttle body cleaner and a soft cloth to remove carbon buildup.
Reinstall the air intake duct and reconnect any sensors.

3. Check and Replace the Fuel Filter (if necessary)

Locate the fuel filter along the fuel line.
Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
Disconnect fuel lines using a fuel line disconnect tool.
Replace the old fuel filter with a new one, ensuring proper orientation.
Reconnect the fuel lines and replace the fuel pump fuse.

4. Inspect and Replace Spark Plugs

Remove the ignition coil covers (if applicable) using a socket set.
Carefully pull out the ignition coils from the spark plug wells.
Remove old spark plugs using a spark plug socket and ratchet.
