When I stop at a light I feel a very rough idle from the engine for about a second. This has happened a few times already. Everything about the car is fine, but every now and then I feel the engine rumble after I come to a full stop. Is this normal V6 vibrations?

With the recent heat wave in our area, this same rough idle has occurred a handful of times, under the almost identical conditions as the OP. Prior to this heat wave, it didnt occur. Looks like I will be reviewing the carbon build up thread.
I would also add that I started my engine and got going, then lost power while I was driving. Check VSC and engine light came on. Pulled over and restarted the engine and the problem never showed up since then. This happened earlier this year.
