sounds like the timing is off, have you had any recent work done on it?

Seems the idling speed is too low. When cold the fast idle would be in operations and the idling speed would be higher so you won't feel the vibrations. Check the idling speed and adjust it if necessary.

The hesitation could be due to ignition timing being too retarded or minor misfiring due to spark plugs or wires.
