At slow speeds, like idling through a parking lot, my DA idles along with a lope to it. Does it in reverse, with or without a trailer. All stock, about 5K miles, only anomaly so far. Is this normal? A search didnt show much on this for the 04.5 LLY. So far, this thing has been awsome, beats the ----- out my '96 6.5TD :ro)

thanks

There's a reflash for this. Their are a few thread topics on this symptom, it's also called "surging" Try searching for that.

I had the same problem. Reflashed, problem gone. JJ
