HELP!! New injectors P2149, P205,P204,P205
 

Initially had a P2150 injector A bank... Ended up replacing all 6 injectors, feed tubes and valve cover gasket..
Truck fired up nicely. Let idle for about 10 minutes while cleaning up... Get in truck to back out for test drive.. CEL came on, started running rough and knocking. Now pull up codes for injector bank B and each individual injectors...Grrrr..... Ohmed out harness and injectors, all show good and consistent to all 6..... Checked connector to gasket, looks good. Plan on pulling the harness this evening and going through it end to end.
But I guess my question is, could it be possible the ECU is having a roving bug and going out? Or anyone with a tip to check... Thnaks in advance.
