vacuum pressure

I am also suffering through the dreaded 'not' 41 41 code. But I suspect it is actually a vacuum issue (mushy brakes, cruise unable to hold, misfire under load). What should the vac be on this 89 2.9? I am getting a very solid, with no needle bounce 35 at manifold.

That seems very high. I would expect to see high teens, low 20's. But it's been a looooong time since I've done any diagnostic work to an engine.
