Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the battery to ensure safety during work 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 area.
Reinstall the air intake duct securely.

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

Locate the IAC valve, which is typically mounted on or near the throttle body.
Disconnect the electrical connector and remove any screws or bolts securing the valve.
Install the new IAC valve, ensuring a proper seal.
Reconnect the electrical connector.

4. Fuel System Inspection and Repair

Check the fuel pump operation by listening for it when the ignition is turned on.
If the fuel pressure is low, replace the fuel filter first, then the fuel pump if necessary.
Ensure that all fuel lines are secured and free of leaks.

5. Clear Error Codes

Reconnect the battery and use the OBD-II scanner to clear any existing trouble codes.
Perform a test drive to ensure that the stalling issue is resolved.
