Update:
So they've been working on my car all day, trying to calibrate the Air-ride. Front left will not "get-right" that's where the work was performed (motor mount). There keeping it over the weekend. So bummed, can't help but feel like all my careful planning and effort in getting a as close to problem-free 4.8 as possible just went out the window w/ one visit to the repair shop. On the "bright side" stopped in today to get my shoes, and the tech working on my car looked focused and through. Didn't look very happy, but he certainly was taking it out on my car. Which is nice I know I'd b pretty fustrated now. Also for the thirty seconds that I did get to drive before the dash lit up, the new motor made a clear differance in response and general feels. I'm stoked on that.
