Yep, basically exactly confirms what my research was saying. I was always looking at it and other pictures going "this doesn't seem right, they always have this connected to something else, and it feels like it's alternating between pulling in and pushing out air."
The PCV line was connected, and the line at the back of the manifold closest to the firewall that goes from valve down to block was connected, but this one wasn't. Time and research later and, voila, engine is running much better.
Last thing is the stall when coming to a stop, but we've already established that I need to recirc, which I'm going to be doing today.
Doesn't help that I have the S14A SR20 as well, so while 99% of the information I find is for the S13 SR, it doesn't always apply in the same way, lol.
