    In response to bowtie44s

I didn't see any disconnected or broken vacuum lines, nor did I hear a vacuum leak when I checked. I haven't sprayed the intake manifold with anything to check the gaskets though. Since it is 49 psi at idle I stopped looking for a vacuum leak and thought it was a fuel pressure problem.
