Thanks for your response. I had no idea the problem would post 5 times - I’m new to this forum, but I thought I was posting only once. Have a little compassion…
Yes to the following: factory alarm.
No to remote starter
Do you have any insight re: the temperature connection? Hot and muggy or just damp and warmish (got caught last weekend in central Mass. - 40 degrees and moist) and/or the fact that just letting it sit has so far ALWAYS solved the problem?
Again, pardon my posting blunder and thank you for responding.
