Rough and shaky idle on a 2002 SL500 (R129)... NEED HELP Please

[Tech-Tune]

My car is experiencing a periodic hesitation when accelerating from low revs.
It also idles rough and has a very noticeable shake when in park and drive.

It drives just fine, but when coming to a stop it starts to surge and when I come to a stop the rough/shaky idle starts up again.

I've already:
-installed 16 new spark plugs
-installed 8 new ignition coils
-replaced both motor mounts and trans mount
-removed and cleaned the TB
-checked all the hoses by the TB (all were connected and seemed fine)

Any help/assistance is greatly appreciated.
