"Of course the leak can be so minor and only occur when the engine goes in Closed Loop."

This does not happen. A vacuum leak is a vacuum leak. It doesn't care about open or closed loop. There's nothing that happens in closed loop that would create a vacuum leak if there wasn't one there already.

Then is there something else that would let the idle be "normal" in Open Loop, but change when in Closed Loop and only change when you are driving, therefore putting a load on the engine?
Could it be something in the PCV system, or have anything to do with the charcoal line, or canister?
Could it be that the "curly" line came loose in its connection but not totally out?

If I start the engine for the first time, and just sit there, which I did on occasion, then the idle is "normal" no matter what I do in either Open or Closed Loop. I can rev the engine 2k or higher and it will come back to normal. It's only when I start driving and by that time the engine is warming up and in Closed Loop, was when I would be getting the high idle at a complete stop.
But then if I pulled over and stopped and shut the engine down, upon restart the idle would be "normal" until the next stop.

I know this is repeating myself from previous posts, but just trying to figure it out and learn along the way.

I also know probably the only way to determine the issue is by process of elimination. After I do whatever I need to do and get it back together, I'll have to see what happens....

Anyway, good conversation from all....appreciated.....
