Recently picked up a great grand marquis with handling package. CEL came on and code reads P0128. Says Coolant Temp Below Thermostat Regulating Temperature.
Anyone else ever see this? Drove car to Florida and back and drove great. Fuel economy seemed a little lower than I hoped but not terrible. Could get 25-26 at 70 mph dropped fast going faster though.
