Hey thanks for your help, I bought one of those boost leak testers and found a good leak right at the throttle body. I had a lot of vacuum leaks when I bought the car and fixed all of those, but until I got something to pressurize the system it was hard to find any other leaks as far as pressure. The little one sounds as if it is coming from the IAC area, not sure if it is internal to that valve, car does run a lot better though. This has obviously been a problem for the previous owner cause when I finally got the leak fixed the car wouldn't idle. The had the adjustment screw turned almost all the way in.
