my 2008 has always idled low and rough as soon as it gets to low it speeds up slightly. Some members have had dealer raise idle speed. I am so used to it after 120000 miles that it does not bother me anymore. My truck is auto so may be different but if this describes your situation it may be normal.

If you get a tuner, i.e. Superchips, you can tweak the ignition timing and the idle...and get a little more power out of her, besides.
