The thread I just referenced is really good, and I definitely have a problem with it occurring fter it sits in heavy rains or snow and does not run for a couple days. Also, I have been told my battery is not passing the load test - even when that was a 3 month old battery. So, perhaps the battery was bad from Autozone (unlikely?) or, as I suspected before I had the ASR issues, the alternator or voltage regulator is fading. A reman ETA was put in this car by the PO, maybe 20k ago. I doubt that's it, but who knows.


Quote from related thread:

"It is the one component whose behavior/ non-behavior would consistently correlate to the temperature/humidity issues I have described throughout this thread. And I have noticed previously, and again in our current cold weather, that the ASR fault does not self-correct until coolant temp reaches 81/82. I will go out on a limb and say there must be a connection."
