6.0 P0284 code
I've had a series of problems with this truck, it has 173k on it. I recently had the #5 injector go bad, I ordered a reman set and reaplced them all, all new o-rings and fire seals. Put the truck back together and now have a miss on #8, I did a scan with the AE (Auto Enginuity) and it did not pass the buzz test for #8. I swapped out the injector with one of my originals, no change at all. I swapped out the FICM with a known good one and it I didn't see the code come back, this morning while driving to work (5 miles after swapping FICM), the miss returned and the same p0284 cyl. #8 contribution fault code returned.
This truck has had the following recently updated/upgraded.
-stand pipes/dummy plugs
-8 reman injectors.
Thanks in advance!
