My girlfriends 92 talon n/t has idle surge which I still haven't solved but when the car is off but the ignition in the acc position the FIAV makes a constsnt buzzing noise until I unplug it or turn off the ignition. I replaced the FIAV (old one did the same), biss,tps, and still don't know whats going on.

-FIAV is none electrical and is located on the bottom (part of) the throttle body, do you mean the ISC (idle speed control servo) locate on the 7:00 area of the throttle when look at it's opening?
