6.0 Running rough for 2-3 miles then quits
I have heard so much about FICM Ed that I just have to throw in my 2 cents, he is a good guy and helps out tremendously when your trying to get your truck fixed. I had strong voltage at my FICM 48 across the board with no dip ever, truck would idle perfectly but after it warmed up it ran like crap, not to mention when you took it on the road after a couple of miles it would stop running.
First thing I did was put the scan tool on it and had a code for a Cam Position Sensor. Changed it out and the stalling stopped but still had no power.
Step two was to get my FICM checked and tuned with an ECO tune, when you cooled the FICM down, the truck ran better. So I sent it off to Ed at FICMrepair.com and like all the testaments before, easy to work with and a quick turnaround with a great FICM in return. More to follow...
Step three was a bad Number 4 injector, passed the buzz test but would start missing when it got hot, while it was cold we could disable it and you would get the miss that you would suspect, but while it was hot you seen no change in engine performance. Changed it out and had the exact same discrepancy, cold good and hot a miss.
Called Ed again and he said it sounded like a bad injector, so after we tried another FICM and it did the exact same thing, we got another injector. Took the new injector and put it in the number 2 hole and pulled the known good number 2 injector and put it in the 4 hole.
Truck runs great and I can't say enough about the advice and customer service that you get from FICM Ed and Moyock Automotive in North Carolina.
Dean, Jeff and Pete you're top notch!
