Chris, the problem is that it does stall, sometimes when cold and sometimes after driving 10-15 miles on the highway as you stop/slow for a turn or traffic light. The last couple of times we drove it, once approximately 35 miles straight, mostly @ hiway speeds and the other times just around town, it has run perfect with no hint at shutting off. It has been in the shop for other work and scanned but gives no codes. The shop owner said it needed to be done by a dealer so they could scan/reset the new unit, all for only $421---so now you see why I am starting to wonder if I really need to have them do it or do it myself and let/hope it resets on it's own. That price seems high since it has only the one bolt and especially if it will indeed reset itself.
