Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is off.
Gather necessary tools and replacement parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Clean the Throttle Body

Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
Reinstall the air intake duct securely.

3. Check and Replace Fuel Filter

Locate the fuel filter (refer to the owner's manual for exact location).
Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
Disconnect the fuel lines carefully and remove the old fuel filter.
Install the new fuel filter in the correct orientation and reconnect the fuel lines.

4. Test the Fuel Pump

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position (do not start the engine) and check the fuel pressure reading.
If the pressure is below specifications, consider replacing the fuel pump.

5. Inspect Electrical Connections

Check battery terminals for corrosion; clean if necessary.
Inspect wiring harnesses and connectors for damage or loose connections, particularly around the throttle body and fuel system components.
Repair or replace any damaged wiring as needed.
