Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure with wheel chocks.
Disconnect the battery to prevent electrical shorts during repair.

2. Inspect and Clean Throttle Body

Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding area.
Reinstall the air intake duct ensuring all connections are secure.

3. Replace Fuel Filter

Locate the fuel filter; consult the service manual for specific location.
Relieve the fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
Disconnect the fuel lines from the filter using appropriate line wrenches.
Replace the old fuel filter with a new one, ensuring correct orientation.
Reconnect fuel lines and reinstall the fuel pump fuse.

4. Inspect and Replace Spark Plugs

Remove the ignition coil covers to access spark plugs.
Use a socket and ratchet to remove the spark plugs.
Check the condition of the plugs (look for wear, carbon buildup) and replace if necessary.
Torque new spark plugs to the manufacturer's specification (usually around 13-15 lb-ft).
Reinstall ignition coils and covers.
