Sounds like you have a vacuum leak somewhere. I believe there is a post or two on here on how to make a really cheap tester for this.

Secondary could be something rubbing or a belt going bad?

Sorry, forgot about this.. Not sure if you still have issues, but check all vacuum lines and chargepipes.
