07max

I have about 300 miles on my new '07 6.0L and have noticed that it idles a little rough @ lights on occation. Could be the larger dispacement engine? I'm coming from a '99 Votec 350, which was not all that smooth. Just wondering if anyone else has noticed this in their 6.0? So far I love the power and can't wait to get it up on the highway!

Thanks,
Steve

Looks like this is a wide-spread issue. They almost got everything right with this new truck!

Mine seems very smooth. I read on that GM Truck site that it may be in the heavy emission control areas. I have not heard anyone around here complaining about it.

I haven't noticed any rough idle at all. Very smooth. Maybe it was some bad gas.

I've experienced the rough idle as well. It only does it when it is started cold. After that, every time I start it there are no problems at all. The link that 07max provided above has lots of other with the same issue, interesting.
