Okay I have 180K+ on my rig and finally lost two injectors, so i went ahead and replaced all eight of them. I replaced a lot of things while I was in there as well, oil cups, injectors, stand pipes, HPOP, upgraded FICM to 58v, IPR valve... maybe some other things. The problem I am having is it seems to have a miss happening ( doesn't matter what rpm ). I had a bad injector and something was wrong with the FICM after I got it back, so both of those issues were resolved. But i still seem to have a miss, also sometime it take 3-4 key cycles to get the truck to start and then it will bellow out black smoke for a bit and have a severe lope to it (almost like it has a cam in it, but that is not happen every time I try to start it. Oh, I knew I had a bad injector and computer because I have access to a snap-on scanner and had codes telling me so, however I have no codes this go around. Any ideas?
