If your coolant temp sensor is bad the ECU will still check for it before the car is started even if you unplug it. Because if the weather is cold, it will go to the cold start enrichment map in the ECU to help with cold weather starting. Disconnecting it will not do anything because the ECU will still see it as a bad sensor. So the ECU still won't switch over the correct map for that temp.

is it possible that the ECU cannot pull the cold fuel map anymore? This might be just a lot of bsing around but maybe someone could swap ecu's and see IF that might be the problem... maybe some DSM's hate the winter.... if anyone has ideas please shoot them up here
