I've notice at idle I can feel the smallest rumble/vibration through my seat. It's random, not constant. If you're not thinking about it - you won't notice it. The tach is ever so slightly jumpy - it moves around about 1/3 of its width of the needle....you can barely see it move. But it does move. I've turned the A/C off as I thought it was maybe that clicking on and off - but no change.
Is this normal and I'm over analyzing - or is something going on?
