Trying to track down an air conditioning problem. Seems like a vacuum leak somewhere is screwing with my AC and shutting it down upon giving it any throttle (hills etc). Where should I look first or is there a certain area that is prone to leaks?...truck is a stock 1993 F-350 460/auto. Thanks!

 

actually IIRC there is a vac canister on that truck check to make sure it's not cracked.
