Solution

1. Preparation

Tools Required:
- Socket set
- Screwdriver set
- Throttle body cleaner
- Clean, lint-free cloth or paper towels
- Safety glasses
- Gloves
Sub-steps:
1. Park the vehicle on a flat surface and set the parking brake.
2. Disconnect the negative battery cable to prevent electrical issues.
3. Allow the engine to cool completely before starting work.

2. Remove the Throttle Body

Remove any components obstructing access to the throttle body, such as the air intake duct.
Disconnect the throttle body electrical connector by pressing the tab and pulling it off.
Loosen and remove the bolts securing the throttle body to the intake manifold using a socket set.
Carefully lift off the throttle body, ensuring no gaskets or seals are damaged.

3. Clean the Throttle Body

Spray throttle body cleaner directly onto the throttle plate and inside the throttle body.
Using a lint-free cloth or paper towel, gently wipe away the carbon buildup and deposits. Be careful not to damage the throttle plate or sensors.
Open the throttle plate manually to access the interior surface and clean it thoroughly.
Repeat cleaning until the throttle body surface is free of debris.

4. Reinstall the Throttle Body

Place a new gasket on the intake manifold if needed, ensuring a proper seal.
Align the throttle body and secure it with the bolts, tightening them to the manufacturer's specified torque (typically around 15-20 ft-lbs).
Reconnect the electrical connector for the throttle body.
Reinstall any components removed during disassembly, such as the air intake duct.

5. Final Steps

Reconnect the negative battery cable.
Start the engine and allow it to idle for a few minutes to ensure proper operation.
Check for any vacuum leaks or abnormal noises.
