Solution

1. Preparation

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

2. Remove Throttle Body

Using a socket set, carefully remove the screws or bolts securing the throttle body to the intake manifold.
Disconnect the electrical connectors attached to the throttle body.
Remove any hoses connected to the throttle body, noting their positions for reinstallation.

3. Inspect and Clean

Inspect the throttle body for carbon buildup and physical obstructions.
If dirty, use throttle body cleaner and a soft cloth to gently clean the inside of the throttle body. Do not use abrasive materials.
Check the throttle plate for free movement; it should open and close smoothly without sticking.

4. Reinstall Throttle Body

Reconnect any hoses and electrical connectors to the throttle body, ensuring they are secured properly.
Position the throttle body back onto the intake manifold and tighten the bolts or screws to the manufacturer’s torque specifications (typically around 15-20 lb-ft).
Reconnect the negative battery terminal.

5. Reset and Test

Start the engine and allow it to idle, checking for any unusual sounds or warning lights.
Perform a throttle body relearn procedure using an OBD-II scanner if required by the vehicle's manufacturer.
