Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench.
Disconnect the battery to prevent electrical shorts.
Gather necessary replacement parts for repair.

2. Inspect and Clean the Throttle Body

Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the interior of the throttle body.
Reconnect the air intake duct securely.

3. Replace the Fuel Filter

Locate the fuel filter (consult vehicle manual for exact location).
Use a wrench to disconnect the fuel lines from the filter (have a catch pan ready for spilled fuel).
Replace the old fuel filter with a new one, ensuring that the flow direction matches the markings on the filter.
Reconnect the fuel lines and secure all connections.

4. Replace Faulty Sensors

If any sensors (throttle position or coolant temperature) were found faulty during diagnostics, remove the old sensor using the appropriate socket.
Install the new sensor, ensuring it is properly seated and connected.
Torque to manufacturer specifications if applicable.

5. Reconnect Battery and Test

Reconnect the battery and ensure all connections are tight.
Start the engine and allow it to idle; monitor for any irregularities.
Conduct a test drive to observe if the stalling issue is resolved.
