Post mercedes 1966 300se w112 auto = inconsistant tick over

please ,please help!
i am having great difficulty in setting up the running /tick over on this car.
It has just had a complete over haul of the fuel injector pump (mechanical)
and re callibrated at least this is not the fault
i am still left with the Merc Dealer that i am useing has been great but obviosly lacks experiance with this 45 year old very complex car.
my problem now is still with the starting and the tick over of the engine .
this has a mind of it's own it can tick over at any thing between 500 rpm to 1200 rpm to even stalling on a regular basis .
the starting when cold is also not at all very good .
i have tried no throttle to half throttle to not touching the throttle all seems in vain the cold start setting has been checked but has not been replaced .
the car when started drives like a new car the engine is very smoth and drives great but as soon as you stop whether the engine is hot or cold and select the gear shift from say forth to park the engine revs are all over the place ???.
we just can't seem to get the engine to run smooth on tick over when hot or cold and as explained it has a mind of it's own and very frustrating as the car is in concours condition and only done 67,000 miles ,
so not knacked
please could you help with any constructive advice on this matter
