This may be a dumb questions, but I have a hiss coming from an area around the manifold side. It could be the lower boot, that oil stick vacuum line, or it just could be the injectors doing their thing. Are you able to hear the injectors? Do they sound similar to a vacuum leak? I'm almost positive there's a leak down there now, but I wanted to make sure I asked about injector noise before taking it to get a smoke test. (cigar method failed :facepalm:)
