Hi,
As far as locating a vacuum leak, there are a couple of ways. First, with the engine running, listen closely for a hissing or whistling sound. Also, using carb cleaner, the engine will increase in RPM's if it's sprayed near or on the leak. Take a look through this link. It explains how to locate and repair a leak.

I attached a pic below showing the charcoal canister filter routing. Check around this area as well. I highlighted several vacuum hoses.
If you have a diagnostic trouble code, let me know what it is. That will point me in the right direction.
Take care,
Joe
