From what I understand from the dealership, Ford knows about the problem but does not know how to fix it. According to the service manager there are three sensors one in the air breather one in the engine and one in the tranny, they all have to be at the same temp to work properly and the ones in my truck are not. They have to come up with another computer to find out which sensor is not working . I have to wait until I hear from them, could be a while.
