It sounds like you have a fuel issue or spark issue. Pull your spark plugs and see how they look. If they look fine then test the fuel pump. You could try to run to fuel system cleaner through the fuel system and see if there is an improvement in idle. Could be any of the following problems,

coil
spark plugs
spark plug wires
fuel filter
fuel pump
injectors
air filter

Check the easy stuff like plugs, wires fuel pump and air filter first.

1996 Ford explorer 6 cyl. shakes at 45-50 mph
If the engine is misfiring and that is the source of the shaking then the check engine light will be flashing like crazy, other wise it is not the engine causing this, I know was a Ford tech for 25 years.
