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.

Could be sticking turbo vanes. There are a number of "How to do it" out there.

Check your ICP sensor and pigtail for any visual abnormalities

The pigtail is specific to the 03 ICP. 04 and above, the ICP is in the passenger side valve cover.

Definitely sounds like a high pressure oil problem. Monitor ICP pressure and IPR duty cycle and verify both readings during power loss and see how that compares to when you feel like you have full power. It could be several things in the high pressure oil distribution system on your 06.
