I just took delivery of new 2007 5.9, six speed manual Mega Cab on Thursday of last week. The truck seems like it is going to be a good runner, it definitely makes more power than my 2004.5 did when new. I am concerned about one issue though. Yesterday morning while driving through town the idle got really rough. The truck ran fine when given throttle but the idle was rough. The truck wasn't fully up to temp and the problem went away after five minutes or so but I'm still concerned. It felt like it was running on five cylinders. The truck only has 500 miles on it, I hope I don't have to take it in for warranty work already. Anybody else have this experience?

Thanks

Gino
