idle vibration/sputter but drives fine

If you think a good mechanic is expensive, try hiring a bad one
Re: idle vibration/sputter but drives fine
The drivers and passengers (left and right) side (or upper) mounts support the weight of the engine and transmission. The engine is the source of vibration so it gets the hydraulic dampened mount.
The front and rear subframe mounts act as the torque limiters, to control or limit the amount of drivetrain rock as you accelerate and decelerate.
They don't really support the weight of the drivetrain at a standstill but they get a workout every time you accelerate.
IMO no, the only goal (as a test) is to space the upper bracket higher so it's not sitting on the base of the hyd. mount, and vibration isn't transmitted into the body (chassis)
I think your lifting the engine up and noticing the vibes disappear pretty much proved it's a mount issue.

By putting washers/spacers under the hydraulic mount bracket, won't it just further compress the mount and risk damage?

I raised the engine a little and snugged it down and now all looks perfect. Good clearance between the bracket and body and the car is smooth as silk again. engine barely shakes in the bay and no more pulsing at idle.
This is a big win! I appreciate you two sticking with me on this and helping out!
