Thanks for the advice. I have been back to the dealer on 5/10 when they replaced the motor mount and then on 5/19 complaining about the same prob--replacing the motor mount did not really help but glad they found it. I have kinda made friends with the Svc Mgr--he recognizes me as I have taken my car in there for oil changes and other service. He rode with me and it was not doing it as bad as it usually does and I told him that it was really bad the day before I could get it back down there. He and the svc advisor say some vibrate worse--but mine never did this before. The air filter has been changed once when I got the oil changed. I have been having it serviced at the dealer regularly since I went year with that light on. I was afraid they would not honor the ext'd warranty if I did not get the thing serviced. So they have made plenty of money off me and stand to make more if they could get this thing fixed.
