Intermittent lack of power
OK. I have a 2006 6.0. I have an intermittent lack of power. Seemingly random times. Some days it never does it. Some days it does it alot. When it occurs the injectors seem to get real quiet. Fuel pressure is good and does not drop while the problem is occurring. I have checked the FICM voltage and it checks out fine, though I have never been able to check it while having the issue.
Ideas?? Chafed FICM wires? Could it be the FICM? I have been searching the forums on several sites to no avail.
No DTCs. It has the blue spring upgrade. I just had the EGR out and cleaned up hoping it was that, but alas still doing it...
I have not owned the truck long. It seems the previous owner may have not maintained the truck very well, judging by the maintenance I have done.
