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?

Throttle blade gummed up? Clean out the throttle body, the blade doesnt need to sparkle, just make sure where the blade meets the bore when its closed is clean of oil and carbon.

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.
