Fitted IAC motor and fault is cured. One thing I did notice and this is an easy test to help diagnose the problem in future. With engine at tick-over gently open the throttle by hand. The IAC "plunger" should follow the motion of the throttle, the faulty one simply re-tracts.
Thanks to all for your interest and replies.
