95 escort vibration

I am working on a 95 escort with a 1.9,it has a vibration at idle.It is worse with the ac on and vehicle in gear.It dosent seem to be a miss seems to run fine.

Where do you feel the vibration the most? Can you tell if it is the left or right side?
Is the vibration only at idle?

Has any work been done recently? Perhaps loose or worn engine mounts?

yes it only seems to do it at idle.i have looked at the mounts and none are broke,maybe a little weak

Well for starters, check plugs and wires. The engine will run on 3 cylinders, so make sure each is working right.

doesnt feel like a miss
