Solution

1. Preparation

Gather tools and parts: OBD-II scanner, throttle body cleaner, screwdriver set, socket set, and safety gloves.
Disconnect the negative terminal of the battery to prevent electrical shorts.
Allow the engine to cool if it has been running.

2. Remove Throttle Body

Locate the throttle body on the intake manifold.
Disconnect the electrical connector from the throttle body.
Remove the air intake duct by loosening the clamps with a screwdriver.
Unbolt the throttle body from the manifold using the socket set (typically T20 or T25 Torx screws).
Carefully lift the throttle body off the manifold, ensuring to not damage the gasket.

3. Clean Throttle Body

Use throttle body cleaner and a clean rag to remove carbon deposits and dirt from the throttle plate and internal passages.
Ensure that the throttle plate moves freely without obstruction.
Inspect the gasket; if damaged, replace it with a new one.

4. Reinstall Throttle Body

Position the cleaned throttle body with a new gasket onto the intake manifold.
Bolt the throttle body back into place, tightening to the manufacturer’s torque specifications (typically around 89-106 in-lbs).
Reconnect the electrical connector securely.
Reattach the air intake duct, ensuring all clamps are tight.

5. Reconnect Battery and Test

Reconnect the negative terminal of the battery.
Start the engine and allow it to reach operating temperature.
Check for smooth operation of the throttle and monitor for any warning lights on the dashboard.
