Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Clean Throttle Body

Tools Required: Throttle body cleaner, soft cloth.
Remove the air intake duct to access the throttle body.
Spray throttle body cleaner into the throttle body and use a soft cloth to wipe away carbon buildup.
Reinstall the air intake duct securely.

3. Replace Idle Air Control Valve (if necessary)

Tools Required: Socket set, torque wrench.
Locate the idle air control valve and disconnect the electrical connector.
Remove mounting screws and take out the old valve.
Install the new idle air control valve and torque screws to manufacturer specifications.
Reconnect the electrical connector.

4. Inspect and Clean MAF Sensor (if necessary)

Tools Required: MAF sensor cleaner.
Disconnect the MAF sensor electrical connector and remove the sensor from the intake.
Spray MAF sensor cleaner onto the sensor elements, avoiding touching them directly.
Allow to dry completely before reinstalling.

5. Check and Repair Vacuum Leaks

Tools Required: Vacuum gauge, hose clamps.
Start the engine and use the vacuum gauge to check for proper readings.
Inspect all vacuum hoses for cracks or disconnections and replace as necessary.
Reattach any loose hoses and secure with clamps.
