Check and Replace Fuel Pump (if needed)
- Access the fuel pump by removing the rear seat or fuel tank cover.
- Disconnect the electrical connector and fuel lines.
- Remove the fuel pump assembly from the tank.
- Install the new fuel pump and reassemble the components.

3. Throttle Body Cleaning

Remove Throttle Body
- Disconnect the throttle body electrical connector and any attached hoses.
- Unbolt the throttle body using a socket set.
- Gently remove the throttle body from the intake manifold.
Clean Throttle Body
- Use throttle body cleaner and a soft cloth to clean the interior surfaces.
- Pay special attention to the throttle plate and surrounding areas.
- Reinstall the throttle body with new gaskets if necessary.

4. Reconnect Battery and Test
