My 2005 HAH (43K miles) has been doing a lot of recalibrations lately. I wonder if it can be related to cold weather. I have seen it do this perhaps 3 times within a week, with 2 or 3 iterations like this within the last month or so. That is, after it has recalibrated and settled back to normal behavior, then within another day or two it might do it all over again. Seems like this happens when it has been especially cold, like 10 degrees F (or less), although the recals occur only when the car has been driven a while (i.e., warmed up). I don't remember such multiple recalibrations when the weather is less cold. Anyone else seeing anything like this?
