Solution

1. Preparation

Gather tools and parts required for repairs.
Disconnect the battery to ensure safety while working on electrical components.
Allow the engine to cool before proceeding.

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 areas.
Reinstall the air intake duct securely.

3. Test and Replace the Idle Air Control Valve (if necessary)

Locate the idle air control valve on the intake manifold.
Disconnect the electrical connector and remove the mounting screws.
Inspect the IACV for carbon buildup; clean if necessary.
If cleaning does not resolve issues, replace with a new IACV.
Reconnect the electrical connector and secure the valve.

4. Check and Replace Fuel Filter (if needed)

Locate the fuel filter along the fuel line.
Relieve fuel system pressure by relieving pressure at the fuel rail.
Disconnect fuel lines carefully and remove the old filter.
Install the new fuel filter in the correct orientation and reconnect the fuel lines.

5. Clear Error Codes and Reconnect Battery

Use the OBD-II scanner to clear any trouble codes stored in the vehicle’s computer.
Reconnect the battery terminals securely.
