Hey u guys do good fast work. Just I feel car has a rumble now when idles. Vibration through floor feel it a bit in seat and steering wheel. Was running good when brought it in. So i wonder what it is ?

Pls post what they find. Let us know if it was "loose lug nuts" from recent service. It's kinda important. If you can't wait until Monday just use your Lug Wrench and see if any of the lug bolts / nuts will easily tighten just a bit when tried. Your symptoms sound familiar.
