I just purchased a 2005 sport trac, I'm really happy with the way it drives. One thing I've noticed is a "hiss" or Vacuum sound coming from behind the instrument panel. It gets louder
as the RPM's increase. This is one of those things that most people wouldn't even notice unless your in the car all the time. Any one else notice this.
