Do you have a code P1537 or 8?
I believe the intake manifold is connected to the IMRC's.
You better see if that's a part you can replace or if yuo have to buy a whole intake manifold. If you didn't actually hear a clatter you would check the wires and connectors.
But hell yeah identify and check that hose out first!
I don't know for sure if it's this hose that contributes to runner control or the year/engine of your truck, but it's often a hidden source of certain vacuum related problems.
