6.0 cyl 4 contribution code after new injectors!
So the whole story is I sent my injectors out and got 190/100s for an upgrade. I never had problems with the stock injectors. So I installed all 8 and it came up with a cyl 4 contrubution/imbalence code. So I checked all 4 on that side and I cracked the plastic on the spool valve wiring on 4 and 6. So I got 2 new ones. Installed them and it still has an audible miss and has the cyl 4 code. I buzz tested them to see if I cracked it again and all 8 passed the buzz test. Could this be a failing ficm or whats the problem here. Id hate to think I just got a bum injector. I need this truck running and im really getting aggravated. Thank you in advance for the help
