Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Clean the Throttle Body

Disconnect the negative battery terminal to prevent electrical shorts.
Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth or brush to clean the throttle plate and surrounding area.
Reconnect the air intake duct securely.

3. Replace the Fuel Filter (if necessary)

Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Locate the fuel filter (usually near the fuel tank or along the fuel line).
Disconnect the fuel lines from the filter, using a line wrench to avoid damage.
Install the new fuel filter, ensuring proper orientation and tightening connections.

4. Inspect and Replace Ignition Components (if necessary)

Remove the engine cover (if applicable) to access ignition coils and spark plugs.
Disconnect the electrical connectors from each ignition coil.
Remove the ignition coils and inspect for cracks or wear.
Replace spark plugs with new ones, ensuring proper gap settings.
Reinstall ignition coils and reconnect electrical connectors.
