Considering what has been done, the problem sounds like a fuel issue. Do a fuel pressure test, it should be 47-50 psi with vacuum line pulled off fuel pressure regulator. If low replace filter and try again. If still low replace pump. Please make sure to rate me when done. Thanks

There is one for the 2003 Mercury Mountaineer. If you are smellign a "vinegar" odor, mix a solution of 1 part bleach to 3 parts water and pour it down the grid at the base of the windshield. It will take care of the smell.

I have a 2003 Mountaineer that had the same symptoms. After doing some research, me and Google decided it was the Blend Door Actuator. It is a fairly difficult job due to having to take pretty much the whole dash off, but I did it myself with minimal experience. I included a few links.
