Thought for sure that was your problem. I even had a few gin and tonics while writing these posts up in early celebration for fixing your problem. :-)
My 81 has a brass tube that hooks into the back of the throttle body. It angles up from the drivers side of the engine. Pretty easy to see if you have one. Mine can fall out of the hole where it enters the throttle body and cause crappy idle and drivability (spelling?) issues.
This and other vacuum leaks can be found with the the pressure check mentioned.
However, I am still a little stumped as to why a vacuum leak would cause intermittent operation unless you are saying the car runs ok for the first 15 seconds - and that is it. Was under the impression it can run good then bad then could bounce back to good.
