When you shut off the ignition, does it " run on ?"
That would be a reason for it to shake.
Give some more info on the car, type and age etc.

i agree, need more info.
is it running hot, does it diesel after you turn it off?
you mentioned idle, is it idling too fast, or where you guessing?
did this just start? have you changed anything in the engine recently?

Idling to fast or not giving it time to drop to a low idle.

if it is dieseling out it could be timing. the best way to check it would be to take off the dist. cap. put a socket and ratchet on the center bolt of the crank pully. turn the bolt counter clockwise untill you see the rotor button move. then turn it clockwise and see how long it takes for the rotor button to move. if it takes a lot before the button starts moving you may need to replace the timing chain and gear. it could be other things also but that could give you a starting point. hope this helps.

Tune it up, make sure your spark is perfect and in time, adjust the idle mixture to highest vacuum.

Check the motor mounts, you will need a crowbar to pry the mount up and down to find a fault.

Try the cheap & easy stuff first. Try turning your idle speed down just a litte bit & see if it helps.
