Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical issues.

Tools Required:

Flathead screwdriver
10mm socket and ratchet
Throttle body cleaner
Soft cloth or paper towels
Safety gloves and goggles

2. Remove the Air Intake Duct

Loosen the hose clamps securing the air intake duct to the throttle body and air filter box using a flathead screwdriver or socket.
Carefully detach the duct from both ends and set it aside.

3. Remove the Throttle Body

Disconnect the electrical connector from the throttle body by pressing the tab and pulling it away.
Remove the bolts securing the throttle body to the intake manifold using a 10mm socket.
Carefully lift the throttle body off the manifold, avoiding damaging the gasket.

4. Clean the Throttle Body

Spray throttle body cleaner directly onto the throttle plate and inside the throttle body.
Use a soft cloth or paper towel to wipe away carbon deposits. Be gentle to avoid scratching the surface.
Open the throttle plate manually to clean behind it and ensure all areas are free of buildup.

5. Reassemble the Components

Place a new gasket on the intake manifold if needed (recommended).
Position the throttle body back onto the manifold and secure it with the bolts, tightening them to the manufacturer's specifications (typically around 15-20 ft-lbs).
Reconnect the electrical connector to the throttle body.
Reattach the air intake duct and secure it with the hose clamps.

6. Final Checks

Reconnect the negative battery terminal.
Start the engine and let it idle for a few minutes to ensure proper operation.
