Solution

1. Preparation

Gather tools and parts required.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is on a flat surface and securely supported.

2. Clean the Throttle Body

Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft brush to clean the interior of the throttle body, removing carbon buildup.
Reattach the air intake duct and ensure all clamps are tight.

3. Replace the Fuel Filter (if applicable)

Locate the fuel filter (refer to the owner's manual for exact location).
Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.
Disconnect the fuel lines from the filter using appropriate tools.
Replace the old fuel filter with a new one, ensuring the flow direction matches the markings.
Reconnect the fuel lines and replace the fuel pump relay.

4. Inspect and Change Transmission Fluid

Remove the transmission drain plug and drain the old fluid into a suitable container.
Replace the drain plug and torque it to the manufacturer’s specifications.
Refill with the appropriate transmission fluid through the dipstick tube or fill port, using a funnel.
Start the engine and cycle through the gears while checking fluid levels and adding as necessary.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored trouble codes.
Start the vehicle and monitor for any abnormal behavior.
