I just got mine out of the Ford shop today with the same problem. Today, while driving, I suddenly got what felt like a clogged fuel filter or bad injector(s). The symptoms were sputtering and poor fuel delivery when on the trottle. While this was happening, the check engine light came on and I limped in to the dealer just barely. It turned out that a P0472 code was thrown which is the EBP Sensor (Exhaust Back Pressure). $425 later ($174 for the sensor and wire harness and rest for labor OUCH!) the problem was fixed. What happened was one tiny wire on the clip harness going into the sensor chaffed and caused the sensor to "think" that there was TOO HIGH exhaust back-pressure and in turn, sent a signal to the turbo telling it to back off and thus no turbo and air mixture being rammed in causing the poor and speratic throttle response.
