Solution

1. Preparation

Gather tools and parts: OBD-II scanner, socket set, throttle body cleaner, rags, and replacement throttle body (if needed).
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery negative terminal to avoid electrical shock.

2. Throttle Body Cleaning

Remove the Engine Cover (if applicable)
- Use a socket set to remove any fasteners holding the engine cover in place.
Access the Throttle Body
- Disconnect the air intake duct from the throttle body by loosening the clamps.
- Remove any electrical connectors from the throttle body.
Clean the Throttle Body
- Spray throttle body cleaner onto a clean rag or directly into the throttle body (avoid excessive application).
- Gently clean the inside of the throttle body, focusing on the throttle plate and surrounding areas.
- Ensure no debris falls into the intake manifold.
Reassemble
- Reconnect the electrical connectors and reattach the air intake duct, tightening the clamps securely.
- Replace the engine cover if removed.

3. Throttle Calibration (if applicable)

Reconnect the Battery
- Reconnect the negative terminal of the battery.
Perform Throttle Position Reset
- Turn the ignition to the ON position (do not start the engine) for approximately 10 seconds, then turn it OFF for 10 seconds.
- Start the engine and let it idle for a minute to allow throttle calibration to occur.

4. Throttle Body Replacement (if needed)

Remove the Throttle Body
- If cleaning did not resolve the issue, remove the throttle body by unscrewing the mounting bolts and disconnecting the wiring harness.
Install New Throttle Body
- Position the new throttle body and secure it with bolts to the intake manifold.
- Reconnect electrical connectors and any vacuum lines.
Final Checks
- Reconnect the air intake duct and ensure all connections are tight.
