Is My FICM Sick?

I'll start with the symptoms:

-Rough cold start, even when plugged in. It seems to shake and miss for a few seconds and then clears up and idles fine.

-Bad miss until warm. If I try to drive it before temps hit over 100*, it will start to miss real bad at around 1500 rpm's. Even with your foot in it, it's almost impossible to go over 35 mph.

-No codes until a few days ago. Starting last weekend, I am getting intermittent codes. Sometimes a P0306. Sometimes a P0300. Sometimes neither. Sometimes BOTH. (P0306, Cylinder 6 Misfire Detected. P0300, Random Cylinder Misfire Detected.)

-Sometimes I can hear the injectors buzzing real good when I turn the key on. Other times, I can hardly hear them at all.

With everything that I have read, it seems to point to a bad FICM. However, my FICM voltage never drops below 47.5 and usually rides between 48.5 and 49. Battery voltage never seems to drop below 11-11.2 during cranking.

With all that being said, there are some heavy zip-ties that are running around the FICM. It leads me to believe that someone possibly broke the clips off of the plugs.

Is it possible that one of the plugs has loosened up? Would that lead to the symptoms mentioned above?

i think you have stiction http://alliantpower.com/sites/allian...01-09r1_en.pdf
plugged in doesn't heat the oil so it wouldn't help the oil fired injectors much being plugged in other than warming up faster

broken connectors are common you can try to fix that first just for peace of mind and you could try a stiction eliminator like hotshots/rev x /archoil

Two bottles of Rev-X were added at last oil change 3500 miles ago. I haven't noticed any improvement.

I can say that some days (very few) it seems to run great. Other days, not so good.

It sure sounds more like injector issues.

The FICM plugs may have been damaged. They usually click in and out nicely, but you have to use the release or it will break the latch. The ties are because of some dummy breaking them, or didn't know how to plug them in.

I had these same symptoms, that ended in a hot no-start condition. My FICM read 48-49.5 (BPD beta test FICM), and my ICP was being screwy. IPR was fine. I've got a 2004.

All 8 injectors needed replacing (which ended up being the HPO leak I had). 177k on original injectors, I guess I can't be too mad hahaha. I also replaced my stand pipes, dummy plugs, and ICP. My truck is super happy! Check your ICP as well.

ICP seems fine. I can't recall what it reads at startup. Pressure is around 575-ish at warm idle.

I haven't had any hard start hot issues.

I am still leaning toward injector issues for you, especially if your FICM is fine. It took awhile for my ICP to crap out on me with those same symptoms you have, just FYI.
