Do I have a vacumm leak? The engine takes a long time to return to idle - say 30 seconds after you come to a red light.
I did a quick check but could not find any obvious leaks.
How is a leak detected and where should I look first?
There is a big metal pipe in back of the throttle body that is probably a good candidate; right?

Doesn't have to be a vacuum leak, might just be the IAC motor not responding properly.
I'd hook up a scanner and look at idle LTFT values and IAC numbers as a first step.
