I must say I'm surprised at the results of my testing today. I really didn't think that increasing the idle timing would make that much of a difference in running temps at stop and go but today proved it. Anyways it was a good day today. I feel I learned something and was able to find a solution to a bothersome issue. It may not be the fix for everybody but it seems to have alleviated my overheating issue. I feel like I can drive the car anywhere in any weather and not have to worry about it. Like I said, a really good day.
