Have you checked all PCV hoses? I also have a Taurus that had similar symptoms, and replaced about $200 worth of sensors and components, and finally took it to a mechanic. It turns out that, on my car at least, there are 3 PCV hoses, one of which ise that is hidden from view, that was badly worn. I replaced the hose for $15, and the car ran like new.
