A lot of cars with a PFC that I have had idle much better with the ISC un hooked. Im sure if you get Chuck Westbrooks notes you can find something about that in them but I havent bothered to get that in depth. However, usually with the ISC un hooked the car does take a little longer to settle on idle once letting off throttle, nothing major but noticeable.
