2. Use a throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
3. Open and close the throttle plate manually to ensure it moves freely.
4. Reattach the air intake duct securely.

4. Check Fuel Pressure

Sub-steps:
1. Connect the fuel pressure gauge to the fuel rail service port.
2. Turn the ignition on without starting the engine and check the fuel pressure reading.
3. Compare the reading against manufacturer specifications. If low, check the fuel pump and filter.
4. If necessary, replace the fuel filter or fuel pump.

5. Verify Electrical Connections
