Solution

1. Preparation

Gather tools and materials: Ensure you have a throttle body cleaner, a clean rag or cloth, and a flathead screwdriver.
Disconnect the battery: Use a wrench to disconnect the negative terminal of the battery to prevent electrical shorts.

2. Remove Air Intake Duct

Loosen the clamps on the air intake duct using a screwdriver.
Carefully detach the duct from the throttle body, taking care not to damage any sensors or wiring.

3. Access Throttle Body

Locate the throttle body: It's typically found between the air intake duct and the intake manifold.
Remove any electrical connectors: Gently disconnect the throttle position sensor and any other connectors attached to the throttle body.

4. Clean the Throttle Body

Spray throttle body cleaner: Apply the cleaner directly to the inside of the throttle body while keeping the throttle plate open (you may need to manually open it with your hand).
Wipe clean: Use a clean rag to wipe away dirt and carbon buildup. Ensure the area is free of residue.
Clean the throttle plate edges: Ensure that the edges of the throttle plate are also cleaned thoroughly to allow for proper sealing when closed.

5. Reassemble Components

Reconnect electrical connectors: Plug back in the throttle position sensor and any other previously disconnected connectors.
Reattach the air intake duct: Align and secure the duct to the throttle body, tightening the clamps properly.

6. Reconnect Battery and Test

Reconnect the battery: Securely attach the negative terminal.
Start the engine: Allow the engine to idle for a few minutes and check for any irregularities.
