Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical hazards.

2. Inspect and Replace Fuel Filter

Locate the fuel filter, usually found along the fuel line.
Use a wrench to disconnect the fuel lines from the filter. Be cautious of fuel spillage.
Remove the old fuel filter and inspect for blockages.
Install the new fuel filter, ensuring the flow direction is correct.
Reconnect the fuel lines securely.

3. Clean the Throttle Body

Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle body and butterfly valve.
Inspect the throttle position sensor for any damage or corrosion.
Reinstall the air intake duct securely.

4. Test and Reconnect Battery

Reconnect the battery terminals, ensuring they are tight and corrosion-free.
Start the engine and allow it to reach operating temperature.
Monitor the engine for any abnormal noises or fluctuations.
