Ford: Ford,87 302, vacuum problem, leaks

Question
I have trouble with my car idling.When it's cold it's fine but after it warms up it stalls a lot.I know it has a vacuum problem because when I accelerate my A/C vents shut down.Any idea's?

Answer
Honestly... try getting the vacume leaks taken care of first... a vacume leak can cause your car to run poorly.... (You can spray brake cleaner around the intake and listen for a change in the engines pitch... ) that should help you find the vacume leak...
