6.0L rough start/idle until warm
Our '06 F450 6.0L has been starting pretty rough lately. If you try to drive it before the engine/trans temps are warm, it runs super rough and spits a little smoke. Oil changes have been at 7,500 mi. like my dealer said but I saw somewhere that a lot of people change at 5K mi. Once the engine/trans are at normal temps, it runs perfectly fine. We haven't done a fuel/water separator/filter change in a while, could this be it?
