Engine Shake

My M119 (500) suddenly developed a pronounced shaking, it was fine when I got to my destination. But started to shake when I started it up as I was about to leave.

Motor and tranny mounts have been replaced about 3000km ago.

Engine seems to be running fine and no misfire, shaking increases when put in "P" or "N", decreases when put in "D".

Any ideas?

Thanks.

Solved the problem, removed the air cleaner and looked around. There is a vacuum line connected right next to the injector for cylinder #1 (cylinder nearest front of car, left hand side when standing in front of the car) It somehow got pulled off, plugged it back in and shaking stopped.
