If you have a Pneumatic Governor a bad Diaphragm or Vacuum leak in the Housing can cause some issues. There has been some within the last week to 2 months threads on that.

Looks like I have a mechanical governor. The pneumatic one is in the butterfly contraption on the intake manifold, which I don't have. That must have been only a 77 thing on the 123s. I've never seen one on any of the 123's I've ever worked on, only on the 115s.
