Thanks for the offer of help but I live in SI. I am going to record the temp when the problem starts. I have Autometer guages so it will be easy to get an accurate reading. I am starting to think maybe I should just change all of the sensors. I have had this car for many years (18 to be exact) and I cant remember ever changing any of them except the o2 sensors. Now all I need is for the weather to break so I can get to work.
