Art, yes the heater in the 02 does require a bit of amperage, so that's most likely where your voltage is going. You said you datalogged your engine while this is happening what inj. pulse are you seeing how bout coil dwell and calculated timing? you should be seeing some sort of change in these, what happens cto the 02 reading?
