I'm cleaning and sorting...and when this hose popped off, I noticed it was plugged. I didn't see this on any of the parts diagrams..correct or no?

Some PO disabled your deceleration valve (which is what that was attached to). The decel valve is used on D-Jet FI cars to protect the MPS during hard overrun, but it has the side effect some people don't like -- slowing engine returning back to idle, especially if it's maladjusted.
They plugged that line so there wouldn't be a vacuum leak. You can run as-is or plumb the decel valve back into your system.
