Solution

1. Preparation

Tools Required: Socket set, screwdrivers, rags, throttle body cleaner, safety goggles, gloves.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Remove Engine Cover

Remove any screws or fasteners securing the engine cover using a socket or screwdriver.
Gently lift the cover off and set it aside.

3. Access Throttle Body

Locate the throttle body, which is typically found between the air intake duct and the intake manifold.
Disconnect the air intake duct by loosening the hose clamp with a screwdriver or socket.
Carefully remove any electrical connectors attached to the throttle body. Use a flat-head screwdriver if needed to release the clips.

4. Clean Throttle Body

Spray throttle body cleaner directly onto the throttle body’s inner surfaces, avoiding the throttle position sensor.
Use a clean rag to wipe away carbon buildup inside the throttle body. For stubborn deposits, use a soft brush.
Open the throttle plate manually (if necessary) to access the interior surface and clean thoroughly.

5. Reassemble Components

Reattach any electrical connectors to the throttle body, ensuring they click securely.
Reconnect the air intake duct and tighten the hose clamp.
Replace the engine cover and secure it with screws or fasteners.

6. Final Steps

Reconnect the negative battery terminal.
Start the engine and let it idle to check for any issues.
