Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Clean Throttle Body

Remove the air intake duct to access the throttle body.
Use a throttle body cleaner and a soft cloth to clean the throttle plate and housing.
Make sure the throttle plate moves freely and there are no obstructions.
Reattach the air intake duct securely.

3. Replace Fuel Filter

Locate the fuel filter along the fuel line.
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 a fuel line disconnect tool.
Replace the old filter with a new one, ensuring fuel lines are connected correctly.
Reinstall the fuel pump fuse and check for leaks.

4. Inspect and Replace Spark Plugs

Remove the engine cover if necessary to access the spark plugs.
Use a socket and ratchet to remove the spark plugs.
Inspect the spark plugs for wear or carbon buildup; replace if necessary.
Gap new spark plugs to manufacturer's specifications before installing.
Torque the spark plugs to the recommended setting (usually around 13-15 lb-ft).
