The egr transducer is supplying vacuum to the egr while at idle. Not supposed to do that. I'm going to swap the turbo transducer with the egr transducer while replacing the vacuum hose. Then check to see if the egr transducer is still supplying vacuum to the egr at idle. If it doesn't that would indicate a bad transducer. The one that's connected to the turbo.
Correct me if I'm going in the wrong direction.

And something else I noticed was the egr valve was still under vacuum with the engine off. That doesn't appear to be right.

Sounds like a bad transducer to me.
