Hi My Durango is running rough.Idle jumps .Its seems to run ok on road but when i stop it idles rough.Could it be plugs.It has champion plugs in it now.Thanks you for your help

Yeah I am having the same problem with my 2001 SLT 4.7 liter. I am going to just give it a full tune-up as it has 30k miles on it. I am going to try Splitfire Spark Plugs as I think this will resolve the rough idle.
