Hi !

My ford has boost loss that apears sometimes. I started watching the turbo actuator and it seems that it's not able to keep it steady. On idle the actuator should be down and vnt open but when its down it has vibrations and sometimes goes back un(vnt closed)

There are no vacuum leaks from the boos controller to the turbo actuator. The boos controller was recently changed. The boost Controller is recieving a steady vacuum.
