Can't thank oldguy enough. I joined a Jeep fb page, just got accepted as it's private, and lo and behold a Jeep off road group said they could diagnose her, just as Oldguy thought.
That's 21 miles south of me by freeway, but also got lots of other thoughts. I think most have been covered already, but can't hurt to get a second opinion...
Mid April I bring her local to a dealer for a recall item anyway. If they can't diagnose I'll see if someone can help me get her to Lakeville to the off road group.
