Replaced rear engine mount with vacuum hose equipped. the mount fixes the bad vibration which was expected however it was also the cause of the fault code which said it had a small gas return vacuum leak egr system. This mount is easy to change if you only leave the transmission mount attached and hold and Jack motor use a small board. Pull motor to front of vehicle and put a jack under rear side of block to twist engine to front allowing enough room to maneuver mount out the top by throttle body. Took an hour if your a seasoned mechanic with the right tools.. If you have low idle speed at stops and still a small vibration, you need to take the top of intake off and clean egr port. In corner also clean the throttle body..
