Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working 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 inside of the throttle body, ensuring the butterfly valve moves freely.
Reattach the air intake duct securely.

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

Disconnect the IAC valve connector and remove the valve from the intake manifold.
Test the resistance of the IAC valve with a multimeter; compare readings to the manufacturer's specifications.
If the IAC is out of spec, replace it with a new part.
Reinstall the new or cleaned IAC valve and reconnect the electrical connector.

4. Inspect the Fuel System

Check the fuel pump operation by turning the ignition key to the "ON" position without starting the engine; listen for the pump's hum.
If no sound is heard, inspect the fuel pump relay and fuse.
Replace the fuel filter if it is clogged or old.

5. Reconnect Battery and Clear Codes

Reconnect the battery terminals.
Use the OBD-II scanner to clear any trouble codes and reset the check engine light.
