OK. I reset the codes on Tuesday, Dec. 18th, and so far no SES light (I've driven about 300 miles). It's running great. I think I'm going to detail it this weekend and put her away for the winter...although I said the same thing 2 weeks ago and have driven it everyday this week! It's easy to say, hard to do.
Thanks to all for the great input. May you and your families have a happy and safe holiday.
