6.0 vibration head ache!
I've got a 2004 F250 4x4 with the 6.0 diesel 300 000 km. Lately it has developed a nasty vibration. Here's what I've got so far:
Cold starting not a problem, no error codes, idle is steady, vibration is most noticeable @ about 1500 rpm and is at its worse when cruising at 80 kph, vibration is less noticeable when in tow/haul mode, doesn't matter whether engine is hot or cold.
I replaced a bad FICM and the situation slightly improved.
