My truck has recently developed a lope at idle. Not visable on the tach but I hear a lope in the "clatter". Enough than my wife asked what was wrong with the truck! Have an Edge, changed settings but that did not help. I guess I will try running it without the Edge. 11k miles, new fuel filter at 8k. Edge has been on for 7k miles and this just started. Could it be the cooler weather (cooler is 70 degrees here in Phx). Other posts regarding idle were ususally about fuel pressure - could this be it? Or is this normal after break-in?
