The last week my 6.0 randomly started idling rough at a stop sign gave it some throttle and it came out of it never acted up again. Started the truck a couple days ago idled rough right away. It has a miss till around 2500 rpm then runs great. Truck has 8k miles on reman injectors. oils changed every 3k miles with arcoil additive. 1500 miles on new motor craft fuel filters and oil. Hooked snap on scanner to it the contribution reading we're all over the place till 2500 rpm then leveled out to 0s. Ficm voltage was hanging around 41v. Bought a reman ficm. Installed it truck acts the exact same only change is that the ficm voltage is at 48v. What else can I check?
