2005 dodge ram 3500,recently started a rough idle at start up.Seems to go away when put in neutral.Runs great at high speeds,has a surge at around 45 when not really accelerating.Feels like it might want to die at stop when in gear,Seems to surge real bad when backing up or going forward real slow.Had trans flushed,ran BG 244 diesel cleaner through.No help

SOURCE: rough idle / engine surges until power is applied

Sounds like a possible vaccume hose leak?

if you are trying to hook up your trailer lights, but there is no pigtail .most all trucks now have a harness behind the tag or rear bumper that will come apart and most parts stores sell a device that will go in between the two haves that makes easy work out of hooking the lights in. without cutting wires and the price is not that expensive
