Tools Required:
- Flathead screwdriver
- Phillips screwdriver
- Throttle body cleaner
- Clean rags or microfiber cloths
- Safety glasses
- Gloves
Safety Warnings:
- Disconnect the negative battery terminal to prevent electrical shorts.

2. Remove the Air Intake Hose

Use a flathead screwdriver to loosen the clamps securing the air intake hose to the throttle body.
Carefully remove the hose and set it aside. Inspect for any damage or cracks.

3. Disconnect the Throttle Body

Disconnect any electrical connectors attached to the throttle body. Use care to avoid damaging the connectors.
Remove the screws or bolts securing the throttle body to the intake manifold using a Phillips screwdriver.
Gently pull the throttle body away from the manifold. Be mindful of the gasket; it may need to be replaced.

4. Clean the Throttle Body

Spray throttle body cleaner directly onto the blade and interior surfaces of the throttle body.
Use a clean rag to wipe away the carbon buildup and dirt. Ensure that the throttle plate moves freely and is clean.
Avoid spraying cleaner onto any electrical components or sensors.

5. Reassemble Components

Install a new gasket if necessary, and position the throttle body back onto the intake manifold.
