Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool before starting work.
Disconnect the negative battery terminal to prevent electrical shock.

2. Remove Air Intake Hose

Use a flathead screwdriver to loosen the clamps securing the air intake hose to the throttle body.
Carefully detach the hose, taking care not to damage any surrounding components.

3. Remove Throttle Body

Disconnect any electrical connectors attached to the throttle body.
Remove the bolts securing the throttle body using a socket set (usually 8mm or 10mm, check specific model).
Gently pull the throttle body away from the intake manifold, taking care not to damage the gasket.

4. Clean Throttle Body

Use a throttle body cleaner spray and a clean, lint-free cloth or a soft brush.
Spray the cleaner onto the cloth and wipe the inside of the throttle body, focusing on the throttle plate and the walls.
Ensure that no cleaner is left on the sensor located near the throttle body. Avoid direct spraying on sensors.

5. Reinstall Throttle Body

Position a new gasket (if needed) onto the intake manifold.
Align the throttle body and secure it with bolts, tightening them to the manufacturer’s specified torque (typically around 89 in-lbs).
Reconnect any electrical connectors removed earlier.

6. Reattach Air Intake Hose

Reattach the air intake hose and secure it with the clamps.
Ensure the hose is fitted snugly to prevent air leaks.

7. Reconnect Battery

Reconnect the negative battery terminal.
Start the engine and let it idle for a few minutes to ensure everything is functioning properly.
