Emissions stuff seems to trip a code more often than not, so I’m also inclined to believe it’s most likely mechanical. I replaced my fuel pump a month ago but didn’t have any drivability issues like what you’re experiencing. Occasional stumble on startup and then one day it just wouldn’t start. It certainly could be that or a fuel filter though. The filter is cheap enough to replace and easy enough to get to. Wouldn’t hurt to baseline it if you keep coming up with dead ends on the vacuum side.
edit: IAC also could be gunked up or malfunctioning. That could explain going from throttle to cruising and it not wanting to maintain a lower engine rpm
