I just replaced those broken hard plastic vacuum lines with rubber ones. With the new EGR valve and sensor, and vacuum lines it runs much better, doesn't stall at all.

But I do notice that after it warms up, if I'm sitting at a traffic light for a while, it will miss occasionally. It doesn't idle rough, it idles smooth, then misses once or twice, then goes back to idling smooth. It will do this a few times if you sit at a traffic light long enough.
