Here the diagram attachedIt is difficult to envision the dislodged. vacuum hoses on your vehicle without an image. If you can take a picture and post that would be helpful. Otherwise find the underhood vacuum diagram and connect lines as shown.
From a view into the engine compartment all you will see is the purge valve under the brake booster. There will be a vacuum hose from the purge valve that connects to a line under the body that runs to the vapor canister mounted on the fuel tank. The purge valve will have another port with a vacuum line that attaches somewhere on the intake plenum.
Follow the larger hose from the brake booster to the intake system. At the intake is there an open port with no vacuum hose attached? If YES this port with missing hose should have to be connected to the purge valve.
This connected vacuum line should agree with the underhood diagram. If the engine stalls at idle with this configuration, it is possible that the purge valve is stuck open. With a stuck open valve the engine is drawing in rich fuel vapors and the overly rich air-fuel ratio is causing engine stall. Just a guess on my part.
