erratic idle speed 700 1988

I am refurbishing a 1988 740T. I notice that when I start the car, the engine will race for a moment, then settle then race again. This carries on constantly while the car is at rest, but in no particular rythm. Is this likely to be the IAC acting up or should I be looking at an air leak somewhere?
Thanks
JD
