So I installed the Jet 180 thermostat about a week ago. Used my Predator to lower the fan settings 20 degrees all across the board. Just got the check engine light. Used my Predator to check the code, and sure enough, it came back with the thermostat message. Something along the lines of, the temp being too low. So anyway I erased the code, but I'm sure it will come back later. What to do now? Adjust the fan settings to something different? Re-install the OEM stat, until summer time? I'm near the San Francisco area. It never gets that cold out here.... :scratchhead:
