Bob [rkerste219] - Along with your post above you had an attached graphic that clearly showed a mechanical shock absorber part [I presumed was the engine shock or damper]. In the POST above as in your first POST you refer to what I know as either the "dashpot" or "vacuum surge damper/dampener".
I can give you advice about both of these but I find it confusing to speak about these together for it makes me uncertain which you are really talking about. So let's pick one and go with it... and then the other.

Stevo - Thanks for trying to help out with our language problem but you might have actually contributed to it instead. What you are calling
" little 'shock absorber' looking thing in the throttle linkage" I think is called either "dashpot" [the term Bob used in his very 1st POST] or "Vacuum Surge Dampener". This simple vacuum "DashPot" does NOT have any mechanical connection to the throttle or IP "linkage" but the Vacuum Control Valve [VCV] to which this DashPot does connect, well this VCV [a $200 piece of plastic] most certainly does.

I have actually been trying to get my hands on one of these to add to my 240D for I believe that these were designed to help delay certain auto tranny shifts... so let me say this in closing:

I have serious doubt that a vacuum dashpot would serve any purpose on Bob's 240D which is a stick shift with an engine that probably came from an automatic.

Concurrently, I would not be at all surprised to find that the stick shift cars had NO "engine vibration shocks".

But on both of the above I canNOT be certain for I am on the road and a bit hampered in confirming these.
