NEW UPDATE!
Ok, disregard last update, becausr this one is more solid of a clue.

I discovered that my car catches idle with no problem so long as I have a vacuum hose unhooked from the intake manifold.

If I leave the evap module hose unhooked from the intake mani and plug the hose, no change, still catches idle.

If I plug the barb for it on the intake manifold, then the car won't catch idle.

SO, the car is requiring this slight leak at the intake manifold, and as long as it has the leak, all is well. I can drive the car as intended, with no issue.

PCV valve could be partially clogged, it also argues for cracking the TB butterfly open a bit more.

As I have said before, older engines tend to need more air to them at idle to stop the die.
