Just sit back and wait for it.....there will probably be questions to you regarding specifics so we can help narrow it down. I had the same question, is it only under load or does it do it all the time?

 

The miss appears at any held speed 35 to 55mph, No codes, no chk eng light, does not appear to miss when acelerate. No miss at idle and at raised rpm staionary no miss.
Feels like you are into a gusting head wind.

 

My 08 does the same thing, feels like a slight engine surge then dip as your driving steady. Been researching and asking around for 2 years and can't seem to find anyone that has had similar issues or fixes.

Runs smooth as butter otherwise, I feel your frustration.

 

Any steady speed between 35 and 50, feels like you have a gusting head wind. At idle no miss and runs smooth. Raise the idle and feels good, no miss. No miss at acceleration. Have changed top plugs and twice gas additive, no help..

 

08's are drive by wire?

 

Yes, 2008-2011 4.7L V8s are drive by wire.

 

JIMBIO.. What have you done to solve problem. Maybe save me time money. How many miles on yours and what mileage did your problem start. How high in dodge management have you climbed thier ladder. Could it be the trans?

 

I have had the truck sense 39K and today it has 71K, the problem is more so noticable when it's cold but everything you describe is what I feel. I have not done anything with the dealer because my warranty is out. I have changed all spark plugs, swapped out the TB, played with all superchips settings, along with normal fluid changes. I believe it is the transmission or a faulty speed sensor (but until someone gets it fixed who knows).

 

I swapped out my cam position sensor and no change. If one of the coils is going bad, will that throw a code?

 

I get this surging when I am slowly climbing a short hill in my development, just allowing it to chug along, its the only time I seem to notice it... It kind of acts like it wants to shift down but then doesnt. Its like its thinking, but I hardly ever chug along so its never been an issue. Does yours do it on the flat?
