The car seems to be running well as it was a well maintained one owner car. The idle shaking is noticable and I would like to fix it if is reasonably easy. But I can put up with it for a while.
No Turbocharger = No Rack Damper.
Not a good pic but the Yellow Arrow points at the Rack Damper.

Also the Rack Damper does not have enough effect to cure some majoir shaking caused by something else.
I believe it was made to take out the extra shake on a new Engine; not to compensate for worn Injectors, tight Valve Adjustments or unevern compression and so on.
