Check to see if you have a spring type clip holding the distributor in. If you do the distributor may have popped up around it. You can fix this by getting a solid hold down to hold the distributor in the block. I thnk a chevy one will work. You might also check the distribuotr weights under the rotor, you may have a broken spring or one off of the pin that holds it in place. You can usually find a racetype setup and use the lowest one they have to give you normal type driving. Also check the vacuum advance and breaker plate. I definitely think this is a distributor problem. Another thing to maybe check is the timing chain. Pontiacs for that period are well known fo rhaving chain problems. If you ended up getting 40,000 on them then it was on borrowed time.
