Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.
Gather tools and parts necessary for the repair.

2. Inspect and Replace the Fuel Filter

Locate the fuel filter (usually along the fuel line).
Relieve 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 line disconnect tool.
Remove the mounting brackets and take out the old filter.
Install the new fuel filter, ensuring correct flow direction.
Reconnect fuel lines securely and replace the fuel pump fuse.

3. Clean the Throttle Body

Remove the air intake duct leading to the throttle body.
Use throttle body cleaner and a soft cloth to clean the inside of the throttle body, removing any carbon deposits.
Inspect the throttle plate for proper movement and free operation. Clean as necessary.
Reattach the air intake duct ensuring all clamps are tight.

4. Replace Spark Plugs and Ignition Coils (if necessary)

Remove the ignition coils by unplugging the electrical connectors and unbolting them.
Remove the spark plugs using a spark plug socket.
Inspect and replace any worn or damaged plugs with new ones, ensuring the gap is set to manufacturer specifications.
Reinstall the ignition coils, torquing them to the specified value.
