Car has been driving wonderful. I came home from driving my usual 70 mile round trip. Got up in the morning and when I started the car the engine shakes very very badly only when idleing. If I rev the engine it stops until it gets back to idleing then the engine is shaking like crazy. Any idea's?

Either the idling speed is too low or there is a misfiring causing the problem. If the MIL is indicating, retrieve the trouble codes and let us know what they are.
