Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Clean the Throttle Body

Remove the air intake duct by loosening the clamps and disconnecting any sensors.
Use throttle body cleaner and a soft brush to clean the throttle body, removing carbon deposits.
Reattach the air intake duct securely.

3. Check and Replace the Fuel Filter

Locate the fuel filter (if applicable) and relieve fuel system pressure by removing the fuel pump relay.
Disconnect the fuel lines from the filter; use safety goggles to protect against fuel spray.
Replace the old filter with a new one, ensuring proper orientation and securing the fuel lines.

4. Inspect and Change Transmission Fluid

Raise the vehicle securely on jack stands and place a drain pan underneath.
Remove the transmission pan bolts and carefully lower the pan to drain the fluid.
Replace the transmission filter (if applicable) and clean the pan before reinstallation.
Refill the transmission with the manufacturer-recommended fluid, using a funnel.

5. Address Engine Issues

If error codes indicate specific engine problems (e.g., misfire, sensor issues), follow the diagnostic procedures to address those codes.
Replace any faulty sensors or components as identified during diagnostics.
