hey jwfrauts....next time your out this way call me... We can have a party for weird running 6.0's lol. Well when I was speaking of high mileage, I put that more in the tune of 200K plus. I mean we should be seeing that not a problem out of a diesel engine. That is one factor that makes us buy it anyway, am I wrong? I havent had time to check anything on the truck, but will get to it this weekend. I guess what aint broke, dont fix it. So I could just drive it until it quits. It runs fine any other time but at idle. It is weird!! Weazel, it feels like its something more, but dont bet on that. I just want it to keep running until I feel safe buying one of the new 2011's!!!!!!!
