94 5.2L Magnum running rough

Today's update:
New plugs, no change.
Just checked fuel pressure: 34-36psi the rough idle made the needle move, 44 psi with vacuum removed.
Service manual says: 31 psi at idle and 39 psi with vacuum removed.

So I'm about 5 psi higher than the book says. Is that enough of a difference to make it run bad?
