Solution

1. Preparation

Tools Required:
- Socket set
- Screwdriver set
- Throttle body cleaner
- Clean rags or paper towels
- Safety goggles and gloves
Safety Warnings:
- Disconnect the negative battery terminal before starting.
- Ensure the engine is cool to prevent burns.

2. Remove the Air Intake Hose

Use a screwdriver or socket to loosen the clamps securing the air intake hose to the throttle body.
Carefully disconnect the hose and set it aside.

3. Disconnect Electrical Connectors

Locate and carefully disconnect the electrical connector(s) from the throttle body.
Ensure no pins are bent or damaged during removal.

4. Remove the Throttle Body

Use a socket set to remove the bolts securing the throttle body to the intake manifold.
Gently pull the throttle body away from the manifold, taking care not to damage any gaskets.

5. Clean the Throttle Body

Spray throttle body cleaner onto a clean rag or directly onto a soft brush.
Carefully scrub the inside of the throttle body, focusing on the throttle plate and the walls.
Wipe away any excess cleaner and carbon buildup until the surface is clean.
Avoid spraying cleaner directly into the throttle body without wiping, as it can cause flooding in the engine.

6. Reassemble Components

Reattach the throttle body to the intake manifold, ensuring to replace any gaskets if damaged.
Torque the bolts to the manufacturer’s specifications (usually around 89-106 in-lbs).
Reconnect the electrical connector(s) to the throttle body.
Reinstall the air intake hose and secure it with the clamps.

7. Final Check

Reconnect the negative battery terminal.
Start the engine and let it idle to ensure proper function.
