Either the ECU sensor is going bad or the ECU has a hiccup.

Do the temp. guage and the fans both run off of the same coolant temp sensor?
Does this sensor have less resistance as the temperature increases?
If so, couldn't you put a resistor between the sensor and ECU, to trick it into thinking that the coolant is cooler than it really is?
BTW: Awsome bus!
