Style chooser

My car have idling problem every morning.
My gearbox is auto.
The car always have high vibration when the car stop on "D".
But this problem go away when is afternoon or at night.
There is no problem for this until i had install turbo.

Could it be:

1) at idle speed, i believe that turbo is turning and i guess there is extra air entering into engine cause too learn?
2) at idle speed, i believe that the inlet pipe is too long and cause less air, so insufficient air into engine cause...
