1986 190E 2.3 8valve shaking at idle


I'm new here and hoping someone can help
My car just began acting up last week with this horrible shaking at idle only and especially if it's in gear. I have to shift the car in neutral at every stop or light due to the shaking. I changed the spark plugs but the old ones still looked and no difference. When accelerating or driving the shaking goes away. Could this be a vacum leak? I heard people say engine mount but won't it shake all the time if it would be an engine mount? Has anybody experienced this. Any help would be appreciated it's driving me crazy.

Mine's doing the same shakeing!!! It only appeared a few days ago. It is quite irregular (appears and dissappears whenever it likes). Btw I run with the EHA disconnected since it won't start cold with it plugged in, whatever, if I connect it when warm it runs and starts over ok!! Any suggestions anyone?

motor mounts, they seem to go out every 75k-100k, especially the exhaust side.
