i have had a problem with my 6.0 for about a month now. i haven't driven it because of the problem. talked with a gentlemen last night about it, he thinks the FICM is going bad. it reads good voltage, but that doesn't mean it isn't going bad. so i am looking for a FICM to borrow and see if that is my problem. didn't know if any one in the ohio chapter has an extra one i could try.
I just went through the whole FICM thing today. Mine was the Cold Start problem. It ran excellent once it was warm and even started great when warm. It would not start once it was cold. Once it did start, it sounded really rough and would even shut off. I thought the FICM only caused cold starting problems, but I could be wrong.
