Quoting E39Alfa:
Shop made the necessary adjustments and vibration is now gone.
Only issue now is the car idle low at times after engine is warm...
CAS probably??
Low idle at times? or all the time? Cam timing be off can cause low idle. Did it have low idle before the timing belt job?

MY MOTOR JUST WENT!!!
NO COMPRESSION in 3 of the cylinders!!!
Here is the series of events that uncovered this mess...
Took the car to another shop (not the shop that did the TB service, of course) to convert my AC to 134A. Serviced and worked fine until AC went out 3 weeks later.
Returned to car to the same shop to find out why my AC stop working after just recently converting to 134A. Shop tested for leaks and what not and found out that the compression clutch was not engaging. FML!!! Just sent $700+ to convert... NOW THIS??
OK fine, I guess no AC for me for the rest of the summer, I can live with that, right??
About a week after that I started to hear a squeaking noise coming from the engine bay... after further investigation found out the belt from the AC compression was loose and part was wedged in the corner of the engine block where the TB cover is.
WTF / HTF was my initial reaction.
Looking down further on the crank pulley, there was only one belt on there. The AC belt seemed to came off the crank pulley and was wedged in a corner. And with the engine running, that was to source if all the squeaking noise with a very slow rotation of the AC belt.
At this point I’m thinking WTF did this shop do when they did my AC service??? So I decided to drive the car back to there shop Sunday evening so they can look at it first think Monday morning.
Well on the 5 mile trip to the shop with my wife tailing me, the car just suddenly died on me at a stop light with no warning sign such as loss of power or engine hesitation/vibration. It just died not even a football field away from the shop.
So after a few F bombs, I gathered myself and popped the hood and saw that now the AC belt was no longer visible in the engine bay. Must have fell to the bottom of engine tray or something. Whatever. So we hook the car with some ratchet straps and pulled it to shop
Shop did their investigation and called me with news that I have bigger problems than the AC compressor and belt...
They did a compression test on the car and received NO COMPRESSION in the first 3 cylinders and didn’t even bother to do the 4th. And that this issue had nothing to do with the AC service that they did because they didn’t touch the AC belt or tension while they did their service. They said that this way an internal issue with the engine at this point. They also took the top portion of the TB cover off and noticed that the belt was starting to shred a bit.
So thinking back to the shop that did my TB service and all the issues they had with it... could it be that my timing was not set correctly amongst other things???
Man I'm lost at this point. Where to start with all this mess???

Nail on the head with opinion # 2 with the crank pulley. It failed!
HOLY HECK!
Are we talking about the crank pulley as in the toothed gear for the timing belt or the crank pulley as in the harmonic balancer that the accessory belts ride on?
ALL DSM's are advanced and ALL Evo's retarded
I love my crazy mother!!!
