Idle speed ok. Square wave with about 60/40 mark/space ratio. 10 seconds later the mark/space ratio changes to 95/5 and the idle speed is up at 1600 rpm. Looks like something is telling the ECU to open the idle valve more. Checked the coolant sensor (again!) and is in spec. TPS ok. Swapped with two other ECUs and the fault persists. Darned if I know!
