This happened to my '04 Bird. It turned out to be the coil packs. At the time, Ford had a recall on the packs and they replaced 7 of the 8 packs. The problem was solved. I also own a '04 Lincoln LS (with the same drive train as the T-Bird). It had the same symptoms but it turned out to be the throttle body controller.
