I am having a similar problem. My car studders when accelerating at any speed, but only when I floor it. This only seemed to start happening after the Ford dealer replaced my dash (recalled). I'm hoping it's just a coincedent.
OK now the strange part. I noticed that it only studders when my tank is less that 1/2, and when it is less than 1/4 it will actually stall. One thing that totally boggles my mind is it always does it when I am making a left hand turn and accelerating. If I'm turning right I can floor it and it runs great!
