I am currently troubleshooting the same issue on a 2003 F250 SuperDuty. It seems intermittent and to only happed under low acceleration when the vehicle is warm around 40-50MPH. I am guessing that it is the TPS (Throttle Position Sensor.) It could also be the O2 sensors but I am going about this in ascending cost order. The dealership indicated that the plugs and coils should be changed. The coils are about $60 each and there are 8 of them. You do the math. I will change them as a last resort. I can't see how a bad coil would cause a miss at very low throttle but not anywhere else in the throttle range. This is why I am suspecting the TPS. I will also change the plugs, air filter and fuel filter today. I'll report back with any information as i know this is a common issue. Incidentally, the vehicl has 78,000 miles on it.

The air filter is in the air box on top of the engine. Disconnect the air intake from the fender, then the wiring to the sensors. The box can now be removed and the filter changed.

It is likely that the crankcase was much too oil. It is likely that the engine would have been damaged if the oil had not be changed.
