Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and the engine is cool.
Disconnect the battery to prevent electrical short circuits.

2. Inspect and Clean the Throttle Body

Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft brush to clean any carbon buildup.
Ensure the throttle plate opens and closes smoothly.
Reinstall the air intake duct securely.

3. Check and Replace Fuel Filter

Locate the fuel filter (refer to the owner's manual for specific location).
Place a container under the filter to catch any spilled fuel.
Disconnect the fuel lines and remove the old filter.
Install the new fuel filter, ensuring the flow direction matches the markings.
Reconnect the fuel lines and check for leaks.

4. Battery and Electrical System Check

Inspect battery terminals for corrosion and clean if necessary.
Test the battery with a multimeter; it should read around 12.6 volts when fully charged.
If the voltage is low, charge or replace the battery as needed.

5. Clear Error Codes

Reconnect the battery and start the engine.
Use the OBD-II scanner to clear any stored error codes.
Perform a test drive to check for stalling issues.
