Hey:
I got a 5.0 that has been rebuilt. The usual rings, seals and what not. Anyhow I was just checking small simple things on my car today. Now I was checking my fuel pressure regulator and there isn’t any fuel that comes out of the vacuum line but when I plug the vacuum line with my finger the engine idles/runs a lot smoother, it doesn’t shake as much if you know what I mean. It also runs rich, you can smell raw fuel inside the cabin. Its stock other than CAI, BBK headers, E303 Cam and MAF conversion. What could be causing this? I will check vacuum and fuel pressure tomorrow night.
