Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to avoid electrical shorts.
Allow the engine to cool down before starting any work.

2. Clean or Replace the Throttle Body

Sub-steps:
1. Remove air intake duct to access throttle body.
2. Use a throttle body cleaner and a soft cloth to clean the inside of the throttle body. Make sure to remove all carbon deposits.
3. Reinstall the air intake duct securely.
Tools Required: Throttle body cleaner, soft cloth, socket set.

3. Inspect and Clean the Idle Air Control Valve

Sub-steps:
1. Locate the IACV on the throttle body.
2. Remove the IACV using the appropriate socket.
3. Clean the IACV with a suitable cleaner and ensure the valve moves freely.
4. Reinstall the IACV and ensure it is securely fastened.
Tools Required: Socket set, cleaner.

4. Check and Clean the Mass Air Flow Sensor

Sub-steps:
1. Disconnect the MAF sensor connector and unscrew it from the air intake.
2. Spray MAF sensor cleaner on the sensing element without touching it.
3. Reinstall the MAF sensor and reconnect the electrical connector.
Tools Required: MAF sensor cleaner, screwdriver.

5. Check for Vacuum Leaks

Sub-steps:
1. Visually inspect all vacuum hoses connected to the intake manifold for cracks or disconnections.
