Solution

1. Preparation

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

2. 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 area.
Reinstall the air intake duct and reconnect any sensors.

3. Replace the Fuel Filter

Locate the fuel filter (if applicable; some models have it integrated with the fuel pump).
Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
Disconnect the fuel lines from the filter (be cautious of any residual fuel).
Replace the old fuel filter with a new one, ensuring proper orientation.
Reconnect the fuel lines and reinsert the fuel pump fuse.

4. Inspect and Replace Air Filter

Open the air filter housing and remove the old air filter.
Inspect the air intake for any obstructions.
Install a new air filter, ensuring it is seated properly.

5. Address Vacuum Leaks

Inspect all vacuum hoses visually and by touch for damage or disconnections.
Replace any faulty hoses with new ones, ensuring a snug fit.
