That is part of what makes me think the sensor is bad. The engine isn't cold, but the system is acting like it is, so it ends up fighting against itself to run rich for the cold, but at the same time it isn't running like it is cold, so it fights back to stoich. Do you per chance have an OBDII device that you can use to monitor what the ECM thinks the coolant temp really is?
