Actually you probably need to reset your adaptations (you never mentioned this), and then it’ll take a few days for it to smooth out.
My bad, you're right, totally forgot to mention, did reset all the adaptations (whoops, bucked like mad until I did the throttle reset!), and I've actually driven it about 500 miles--still a little rough. Before resetting the fuel trims were close to -10%, likely because of the leaks I'd fixed, but now it is back around 5%.

The thing is, it used to idle smoother, so I feel like it definitely /can/ idle smoother, but I'm running out of things to replace!
