Solution

1. Preparation

Tools Needed:
- Socket set
- Screwdrivers (flathead and Phillips)
- Throttle body cleaner
- Clean rags
- Safety goggles
- Gloves
Safety Warnings:
- Disconnect the negative battery terminal to prevent electrical shorts.
- Allow the engine to cool before starting the cleaning process.

2. Remove the Air Intake Duct

Locate the air intake duct connecting the air filter box to the throttle body.
Use a screwdriver or socket to loosen the clamps securing the duct.
Carefully detach the duct from the throttle body and set it aside.

3. Access the Throttle Body

Disconnect any electrical connectors attached to the throttle body by pressing the release tab.
Remove any additional components blocking access, such as vacuum hoses or sensors, if necessary.
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 generously onto a clean rag or directly into the throttle body, avoiding the throttle position sensor.
Use a soft-bristled brush to gently scrub away carbon deposits and buildup on the throttle plate and walls.
Wipe down all surfaces until clean, ensuring no debris falls into the intake manifold.

5. Reassemble Components

Install the throttle body back onto the intake manifold and secure it with bolts, torqueing to the manufacturer’s specifications (typically around 10-15 Nm).
Reconnect any electrical connectors and hoses that were removed.
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 for a few minutes to ensure proper operation and check for any leaks.
