Hi, BigMase; Wow. There are soooo many possibilities here. Fords are very persnickety regarding fuel delivery. I'd check the fuel filter, first. The slightest blockage could be the problem. Next, clean the throttle body, the idle air control motor, and the MAP sensor. Not common on Fords, but could also be a faulty CTS (coolant temp sensor). That sensor tells the computer the engine temp, then decides whether to lean or enrich the fuel delivery. As you know, fuel injected vehicles do not have 'chokes'. They rely on multiple sensors for inputs to the computer for fuel, ignition, ect.
Good luck. If you have any questions, feel free to reply.

LOL. We have 'pet' names for some of the cars. Mercury Vomit (comet) is one of my favorites.

Persnickety is right. It's definite old enough to need a good going over. If you want some DIY items try fuel filter and see if any air hose (those small ones all over the engine) are cracked and leaking. It's definitely time for a lot of little items like this to be replaced.
