I have a 2002 V6. Most of the time when I accelerate, it takes a while to get some speed. Sometimes as I'm accelerating, I hear what sounds like a backfire, a deep 'poof' 'pop' sound, sometimes from under the hood. When I brake to a stop, my RPM's go down under 1K, and it shakes a little like it wants to turn off, then it idles fine. Is there anyone out there who could help me diagnose what is going on with my Mustang?

sounds like you need a tune up.
