Thanks Jack, When I got the car 2 years ago I replaced all the little vacuum line connectors I could find under the hood. I guess that I'll have to go to town on her.
I've heard of mechanics using smoke to test for vacuum leaks, is there a way for anyone to do this or does it require special tools?
