This has turned out to be bad injectors for the most part. And it seems to be a problem with early build engines. My build date was 1/5/04,
I cannot get D'ambrosio to return my phone calls

KFette, thanks for replying in about your 305/555. It seems to be luck of the draw on the mileage issue. Maybe some motors are just wound tighter than others from the get go... who knows. My 600 is doing around 16 mpg, same with my Dad's who has an early Jan. build date. My build date is 12 Mar, best truck I've ever owned
