The vibration only happens in a specific band of acceleration that represents perhaps 20% of the range, if 1/10 is barely accelerating and 10/10 is full throttle. The vibration stops once the car has reached about 25 mph.
Can anyone shed some light on where to start looking?

I have taken it to two dealerships with no results so far, although that is a long story in itself. The next step is going to be to teach my wife how to reproduce the problem and have her take it to a different dealership near where she works. Any insight would be helpful though.

Thanks!

It is the round motor mounts. I had the same problem. Dealerships were USELESS MORONS. The mounts get hard, but physically look ok. The perpetrators are the 1--one beside converter down at the firewall. Also described as the R side one because the pulley end is known as the F side. 2-- AND the L side one down by the radiator. 3-- AND the trans. mount on driver side. Lesser probability is the top small bushing sticking out at top of engine, but it TEARS EASILY. You can change it once a year!!! POOR FORD/VOLVO DESIGN. Used Ford Brand Parts [FordPartsGIANT.com] lowest prices, but STILL EXPENSIVE, and it worked!!!! AFTERMARKETS WERE STILL HARD, gave ROUGH RIDE.

Motor mounts---IF THEY ARE NOT CRACKED, -ALL of them 'LOOK' good just by looking at them. They get hard like a rock and look allright and give out vibrations galore!!!! If it has high miles, replace ALL with ----$$$$$$$$$$ Motorcraft brand[better made, last longer]. WILL solve vibrations as you described, as it did with mine

MOTOR MOUNTS. The one behind and below the upper intake[R side] caused my vibration. I changed all the others, but did not help. Mount gets hard from the heat, but it looked brand new, no cracks anywhere. Bought Motorcraft $$$$$$$$$$ one, because it is better quality made, and don't want to do the job all over again!!!!!!!!!----- ONLY a slight vibration is felt in D, upper torque strut bushing needs changed again, BUT, that TERRIBLE VIBRATION is gone, runs, drives out smoother, the smiles returned!!!!!!!
