Question: hissing noise coming from back side of engine

My 2004 Ford F-150 FX4 would always stall whenever I would sit at a stop light or idle. My buddy and I crawled under the hood and found a vacuum hose that was shredded, well missing about 3-4 inches anyways looked like someone cut it on an slant! I have heard several complaints about this on these models but no one can ever tell me the part or the name of the tube that i need to replace we plugged the tube with a screw which stopped the stalling issue but the truck still has the hissing noise don't have the time or money right now to buy a book with and engine diagram either!
