			One of the connections might have came loose enough to open up. A simple bump in the road might have caused it to reconnect enough to were you don't have a vacuum leak right now. I suspect it's the connection under the car. Your car will have a choppy idle. Kind of sounds like it's a V8 with a big cam. You say you lost braking ability too, and that why I suspect that line.
