Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, cleaning spray (throttle body cleaner), lint-free cloth, screwdriver, torque wrench, safety goggles, gloves.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the engine to cool completely before beginning repairs.

2. Remove the Throttle Body

Locate the throttle body on the intake manifold.
Disconnect any electrical connectors attached to the throttle body.
Remove the screws or bolts securing the throttle body to the intake manifold using a socket set.
Carefully lift the throttle body off the manifold, ensuring no debris falls into the intake.

3. Inspect and Clean

Inspect the throttle body for dirt, carbon buildup, and damage.
Use throttle body cleaner and a lint-free cloth to clean the interior surfaces of the throttle body, including the throttle plate and bore.
Ensure that the cleaning solution does not leave any residue.

4. Reinstall the Throttle Body

Place the cleaned throttle body back onto the intake manifold.
Secure it with the screws or bolts, tightening them to the manufacturer's torque specifications (typically around 15-20 ft-lbs, but verify in a service manual).
Reconnect all electrical connectors that were disconnected during removal.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the engine and allow it to idle for a few minutes to ensure the throttle body recalibrates.
Check for any error codes with the OBD-II scanner and clear them if necessary.
