Ok thanks. I was thinking a vacuum problem but just didn't know where to look.
You can look here to view an example of how the system works.

Google for images of the reservoirs, then look under the doghouse, infront of the fire wall and find yours. Connect your vacuum gauge to the dash side of the reservoir start the engine and make sure that the vacuum holds when you turn the engine off. Then find and check each individual line using the gauge. When you find one that won't hold a vacuum you have found your leak.
Mityvac is a great tool and available from almost any auto parts store. HFT carries their own brand but I don't know how good it is. The Mityvac at HFT is $43 and their store brand is $25.
There's a ton of trouble shooting info, read, check, read...
