I have the intake manifold out, had the plenum off and have just replaced the gasket between the manifold and the plenum.

Behind the throttle body, into the plenum on the right side are two hoses, the bottom opening on the plenum floor just behind the throttle body. The hose is hanging free and I see it's damaged, probably happened in the manifold removal. I see that just inside the clip on the away end, where it split, is a small brass venturi.

I can see how this would have a major effect on idle. Anything special about the hose, e.g. can it be replaced and the venturi moved to the new hose? I was surprised to find the little bugger in there.
