Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, throttle body cleaner, vacuum gauge
Disconnect the negative battery terminal to ensure safety.
Allow the engine to cool before starting any work.

2. Clean the Throttle Body

Remove the air intake duct connected to the throttle body using a socket set.
Spray throttle body cleaner into the throttle body while manually opening the throttle plate.
Wipe away carbon deposits with a clean cloth or scrub brush, ensuring not to leave any residue.
Reinstall the air intake duct securely.

3. Replace the Throttle Position Sensor (if necessary)

Disconnect the electrical connector from the TPS.
Remove the TPS from the throttle body using the appropriate socket.
Install the new TPS by aligning it properly and securing it with bolts.
Reconnect the electrical connector.

4. Check for Vacuum Leaks

Inspect all vacuum hoses connected to the intake manifold for cracks or disconnections.
Use a vacuum gauge to test for proper manifold vacuum; replace any faulty hoses or components.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any error codes from the vehicle's computer.
Start the engine and allow it to idle for a few minutes to let the ECU recalibrate.
