Sorry, no answer for you, but I have the same problem with my 2007, AWD 40k miles. Sputters at idle, runs fine otherwise. TCL, check engine and E-Brake light are on (e-brake is not set).
I'm about to take off on a trip (driving my trusty VW) but when I return I may change the plug wires and plugs. Who knows... it feels like a misfire of some sort so maybe the code isn't far off.
Did you find a solution?
