Has the check engine light come on? There are a few things that can cause this. That is why I am asking about the light. It will help narrow down the problem.

Let me know.

Thank's Joacb, as it turned out the fuel pressure regulator was leaking fuel into the vacume source.
A new regulator and away it went.
