Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to avoid electrical shock.

2. Clean the Throttle Body

Remove the air intake duct by loosening the clamps with a screwdriver.
Use throttle body cleaner and a soft cloth to clean the inside of the throttle body, ensuring all carbon deposits are removed.
Reinstall the air intake duct and tighten clamps securely.

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

Locate the IAC valve, typically found on or near the throttle body.
Disconnect the electrical connector and remove the mounting screws with a socket set.
Replace the old IAC valve with a new one, ensuring it is seated properly.
Reconnect the electrical connector and double-check the installation.

4. Inspect and Clean Fuel Injectors

Remove the fuel rail by disconnecting the fuel lines and bolts securing it to the engine.
Remove the injectors from the rail and use a fuel injector cleaner to clean them thoroughly.
Reinstall the injectors and fuel rail, ensuring all connections are tight.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the engine and let it idle to see if the stalling issue persists.
