what could cause this weird idle behavior on a E36?

idles all over the place, but constantly climbs up to 1500 rpm's sitting at an intersection.
now it surges up & down 1200-1500, 1200, 1500.
ICV was just replaced - still doing it.

I recall I had this behavior when an 02 sensor went bad waaayy back.
anywho the car is turbo'd but this all going on while not in boost but in stock vacume, especially when its idling at a stop light..


*oh, also any one got a peak scanner?
