Check your rear motor mount (the dog bone mount). While you're at it, might as well check your other two mounts, got brand new tires ? ran over a curb or anything lately? if so could have a bent wheel

I have a 1997 Ford expedition Eddie Bauer edition that is vibrating when accelerating to a certain speed
could be a engine mount, any engine setting out of line will add more load to the engine mount movement, air leak in manifold, bad spark. it could als be something as simple as a thrown wheel balance or the balance on drive shaft balancer is out of sync, or missing.

Sounds like a bad spark plug, spark plug wire. Probably the spark plug wire. They usually act that way when load is applied. It may misfire under light load and not at idle. Try plugs and wires.

If your car can get up to 30 MPH or more it is not your fuel filter. You need to check your Idle Air Control VAlve and your EGR valve. Also while you are in there go ahead and check your air filter and make sure it is not clogged very bad for some reason
