When checking the secondary vacuum pump and line going under the plenum for a vacuum leak, does that same line going to the plenum pull vacuum at idle ?...

i.e. at idle if disconnected the line has engine manifold vacuum, wondering if this indicates a bad reservoir or check valve? Or is that normal?
