My husband and I just brought home our new 2012 Frontier SL Crew Cab last night, and just a few minutes ago after reading this thread, I ran out into the garage to check out the idle...

We test drove the same truck a few weeks ago, and my husband owned a new 2005 Frontier LE Crew Cab for a while.  This idle shutter has never been noticed...and we are car people. 

What I did notice was that while I was waiting for the engine to "settle down" after initially cranking it up (here in the Atlanta area, it isn't too terribly cold) was that the engine seemed to rev up, then back down, then back up, through about 3 cycles of this before it finally settled in.  At that point I began playing with all combinations of rolling my windows up and down, simultaneously even....Nothing.  There was no change in the idle no matter what I tried to do.

Hope this helps!  Note that we have the SL model, not the SV model.
