Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety.
Allow the engine to cool if it has been running.

2. Remove the Throttle Body

Tools Required: Socket set, screwdrivers, torque wrench.
Locate the throttle body assembly.
Disconnect any electrical connectors attached to the throttle body.
Loosen and remove the intake duct connected to the throttle body.
Unbolt the throttle body from the intake manifold (typically 4-6 bolts) using the socket set.
Carefully lift the throttle body off and set it aside.

3. Inspect and Clean the Throttle Body

Inspect the throttle plate for carbon buildup or debris impeding movement.
Use throttle body cleaner and a soft cloth or brush to clean the throttle plate and bore.
Ensure the throttle plate moves freely without sticking.
If the throttle position sensor is included and shows signs of wear, replace it.

4. Reinstall the Throttle Body

Position the clean throttle body back onto the intake manifold.
Torque the mounting bolts to the manufacturer's specifications (typically around 15-20 ft-lbs).
Reconnect the intake duct to the throttle body.
Reattach any electrical connectors previously removed.

5. Reconnect Battery and Test

Reconnect the negative terminal of the battery.
Start the engine and check for proper idle and throttle response.
Clear any error codes if present.
