Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, cleaning supplies (throttle body cleaner), multimeter, safety glasses, gloves.
Disconnect the negative battery terminal to prevent electrical shorts or shocks.

2. Remove Throttle Body

Sub-steps:
1. Locate the throttle body on the intake manifold.
2. Disconnect any electrical connectors attached to the throttle body.
3. Remove the air intake duct from the throttle body.
4. Unscrew and remove the throttle body mounting bolts using the socket set.

3. Clean Throttle Body

Sub-steps:
1. Use throttle body cleaner and a clean cloth or brush to remove carbon deposits and dirt from the throttle body.
2. Ensure the throttle plate moves freely and is not sticking.
3. Allow the throttle body to dry completely before reinstalling.

4. Reinstall Throttle Body

Sub-steps:
1. Position the cleaned throttle body back onto the intake manifold.
2. Install and hand-tighten the mounting bolts, then torque them to the manufacturer's specifications (typically around 89-100 in-lbs, but consult a repair manual for exact values).
3. Reconnect the air intake duct and secure it properly.
4. Reconnect the electrical connectors to the throttle body.

5. Reset System and Test

Sub-steps:
