Diesel idle shake

Hi Scott,

I have a 79 300SD with 200k miles. 

It runs very smooth except when I idle. 

I put it a new set of injectors and ran a diesel purge. 

The motor mounts don't look like they have any play when the engine is running. 

Any suggestions?

When you say the engine mounts don’t look like they have any play, have you load tested them? Or are you just eyeballing it?

I ended up having new mounts installed this week and it's still shaking. I noticed that it shakes more when it's warm. (Less shake during first morning starts)
