Solution

1. Preparation

Tools Required:
- Screwdriver set
- Throttle body cleaner
- Soft cloth or rags
- Socket set
- Torque wrench (if applicable)
Disconnect the negative battery cable to prevent electrical issues.
Allow the engine to cool before beginning work.

2. Remove the Air Intake Duct

Locate the air intake duct connecting the throttle body to the air filter box.
Using a screwdriver or socket set, remove the clamps or screws securing the duct.
Carefully disconnect the duct from the throttle body, taking care not to damage any surrounding components.

3. Access the Throttle Body

Disconnect any electrical connectors attached to the throttle body, noting their locations for reinstallation.
If applicable, remove any additional components (like the intake manifold cover) that may obstruct access to the throttle body.
Use a socket set to remove the bolts securing the throttle body to the intake manifold.

4. Clean the Throttle Body

Spray throttle body cleaner directly onto the internal surfaces of the throttle body.
Using a soft cloth or rag, carefully wipe away carbon deposits and contaminants. Avoid using metal scrapers that could damage the throttle body.
Open the throttle plate manually (gently) to clean both sides thoroughly.
Allow the cleaner to evaporate completely before reassembling.

5. Reassemble Components

Reinstall the throttle body by securing it with the bolts removed earlier. Torque to manufacturer specifications (check service manual for exact values).
Reconnect any electrical connectors and ensure they are secure.
Reattach the air intake duct, securing it with the clamps or screws.

6. Final Checks

Reconnect the negative battery cable.
Start the engine and allow it to reach operating temperature. Idle should stabilize after a few moments.
