It seemed like people were trying to help you figure out what was going on. What you posted, an the others replies ,were at least $1500 worth of diagnostics, from a dealer, being time an expertise. Have you learned anything new? Did you find a good shop in your area, that you feel ,can help; an if so, will you please post your findings? Sorry to admit, I can't contribute anything useful to help you, but what you find, will help me. Thank you in advance. Steve
