The vac specs Shawn quoted are right on.
Have you pulled codes yet? You just need a paperclip to do it. That's the place to start - it might save you some time bud (and no, the CEL doesnt have to be or have been on for codes to be stored).
Good luck.
Have you guys had a vac leak create knocking?
If you have a factory GT, you are OBD-I and the test connector is on the passenger side of the engine compartment between the firewall and strut tower. We use 3 digit codes.zZsKyZz said:How do I pull engine codes with a paper clip?! I thought I needed a code reader.

And do you really think an exhaust leak would make it idle funny?

Like you said, the header/head point probably isn't leaking, but you do have an aftermarket H-pipe...check where the headers meet the H-pipe. I had a leak there when I first put my BBK on, and the car was idling poorly (though not half as bad as your describing).
I still think it's a vacuum leak or a combination of a vacuum leak and ****ed timing, but you should check everything you can to isolate the problem.
