UPDATE: The same day that the problem occurred and not wanting to take a chance on this part failing for good the next time, I called around. The Oreilly's and AutoZones had reman parts that all had 1 year warranties. The prices were about $250-260 a pop, some with core charges.
I decided, don't know why, to call a local Ford dealership to see what their price was. Surprisingly, the guy in the parts department quoted me $98 + tax (~$106 out the door)! I was shocked. He said that the TAC Module (Throttle Accelerator Control) has been just randomly going on all sorts of cars. Some cars, like the newer Mustang and some Fusions have had recalls made. Unfortunately, my Taurus' VIN
did not have a recall for this.
Long story short, if your TAC starts stumbling and you get a P2111 code thrown, call your local Ford dealership before trying the aftermarket guys. I never thought I would be saying something like that but apparent Ford doesn't want this part to cut into their bottom line, so they've drastically cut the price (by more than 200 bucks!)
