Since the "expert" MB mechanic can't seem to tell what the problem is, I can't do much worse by guessing.

Things that are in need of replacement at 100K...spark plugs at least. You may also have a bad coil or two. The tech can check these easily.

Also, a bad MAS and an ailing fuel pump can set off misfire codes (as was in my case).

Bottom line is this could set you into just under $2K if you let the tech just start replacing all of what I mentioned. For starters, if the plugs and MAS are original, I would get those done first.
