1994 Dashboard Panel Vent problem

[jalangst]

I know it's a vacuum problem with mine. I've seen some people say you've got a leak somewhere. I pulled all my lines and checked them out. They look crack free. I figured since it lost vacuum hold only when I accelerated it was just a small leak and then wasn't strong enough to hold it at that point. I'm not sure. If anyone has any other ideas, let me know.
