Solution

1. Preparation

Tools Required:
- Screwdriver set
- Throttle body cleaner
- Clean rags or paper towels
- Torque wrench
Disconnect the negative battery terminal to prevent any electrical issues.
Allow the engine to cool if it has been running.

2. Remove Air Intake Duct

Sub-steps:
1. Locate the air intake duct connected to the throttle body.
2. Use a screwdriver to loosen the clamps securing the duct.
3. Carefully detach the duct from the throttle body and set it aside.

3. Access Throttle Body

Sub-steps:
1. If necessary, remove any electrical connectors or sensors attached to the throttle body.
2. Unscrew the throttle body mounting bolts using the appropriate socket.
3. Gently pull the throttle body away from the intake manifold, ensuring no gasket material is left behind.

4. Clean Throttle Body

Sub-steps:
1. Spray throttle body cleaner onto a clean rag or directly into the throttle body.
2. Use a soft brush or cloth to scrub away carbon deposits and dirt, paying special attention to the throttle plate and inside walls.
3. Wipe down the area thoroughly with a clean rag until it is free of debris and cleaner.
4. Ensure that the throttle plate operates smoothly without obstruction.

5. Reassemble Components

Sub-steps:
1. Place a new gasket on the throttle body if needed.
2. Reattach the throttle body to the intake manifold using the mounting bolts. Torque the bolts to the manufacturer's specifications.
3. Reconnect any electrical connectors or sensors you previously removed.
4. Reattach the air intake duct and secure it with clamps.

6. Final Checks

Reconnect the negative battery terminal.
Start the engine and allow it to idle, checking for any irregularities.
