Yes, it does. Which is partly why they installed mounts. If you have ever had them replaced once they were worn, the difference is significant in terms of vibration at idle. With 195K on the clock who knows when they were last replaced.

Good reference thread on the issue - I Can't Believe How Smooth My Idle Is Now!!!

When people say their engine 'shakes' at idle, it's tough to know online if they mean it is not running smoothly, or if they are feeling excessive vibration through the chassis. Which is why - after the OP stated the engine has been tuned - mounts are usually a good second culprit. Easy to mistake the vibration from worn mounts for a rough-running engine.

With that age/mileage I would also check the injector seals.
