cataylyst incomplete p1000

What is your question?

Scan tools tell me there are no dtc's in computer, but when obd 2 monitor tests are run I keep getting catalyst incomplete after doing all of the ford specific drive cycle requirements, car is running really bad, I have some kinda vaccum leak because with the car at idle when I barely press the accelerator I hear a whistle sound as if someone was sucking in air to whistle, I just replaced all of the 4 oxygen sensors because the upstream o2 sensors failed min. low voltage tests, and there was a loud buzzing sound under car which I found was the o2 sensors, now the 2 upstream are buzzing again and the cat by drivers side is making a weird humming noise
