Help vacuum leak
So I've wondered and wondered what's been wrong with this mustang I bought. It's a 94 5.0 always wanted one bought it cheap expecting to fix it but I'm stumped. So it's had a bad idle ever since I got started replacing the usual like the maf and iac so recently I was gonna replac the intake manifold gasket and realized a hose that goes under it is missing. So there the leak and so when I look up the hose it's the one that goes to the canp but there's already one connected to it. So I'm asking if anybody has a good diagram with pics I'm pretty new at this or could someone help me figure out what these dudes before me did

Vacuum leaks can be difficult to locate on your own. Look for a performance shop, Automotive Dealership, or service station that has the ability to perform a smoke test. The smoke test will take out all the guess work by locating your leaks and that would be a great starting place.
Once all vacuum leaks are replaced, I would run the following tests, KOEO, KOER, cylinder balance test, etc. http://www.muscularmustangs.com/test1.php
At this time it would be a great idea to perform a full tune-up (oil, transmission, rear diff. fluid change, spark plugs, spark plug wires, cap and rotor, fuel filter, and any other parts/sensors that may need replacing. Make sure you replace sensors with OEM ones, the quality is 10x better.

It's not just a vacuum leak it's the actual hoses not connected to the right place I see other car pics and diagrams and the pcv valve hose is supposed to go under the intake manifold but then there is a hose missing so I need a description of where the hoses go

look on the corral, I believe there is a diagram on there.
