Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface and engine is cool.
Disconnect the negative battery terminal for safety.

2. Clean the Throttle Body

Remove the air intake hose connected to the throttle body.
Use throttle body cleaner and a soft cloth to remove any carbon buildup.
Reattach the air intake hose securely.

3. Test and Replace the IAC Valve (if necessary)

Locate the IAC valve, typically near the throttle body.
Disconnect the electrical connector and remove the mounting screws.
Inspect the IAC valve for carbon buildup; clean or replace as necessary.
Reinstall the IAC valve and reconnect the electrical connector.

4. Check and Replace Fuel Filter (if needed)

Locate the fuel filter, usually along the fuel line under the vehicle.
