Check your intake and make sure no bolts are loose. Im still a noob, but when I was trying to get my 86 N/A's engine to come back to life, the last hiccup I had was that it would start and then immediately die. Turned out my intake had a couple of loose bolts and wasn't fully sealed. Started right up once I tightened them. Im theorizing here but it could be that something similar is happening to you but it only barley jimmies a little loose for just a moment while vibrating, looses the seal, stabilizes, gos back up in rpms and just keeps repeating until it manages to push above the threshold. Im probably talking out of my *** but it would be a pretty quick thing to check. That and your vacuum lines.
