ok. installed harness, which by the way I had to change two connectors on so they would fit, but now alternator light on even though it is charging 14.2v. Anyways, replaced the damaged harness and replaced number 4 injector because it failed contribution test. At first when I viewed data It would not show up any per del on any cyl period. Now I have showing 3,5 and 8 over 3 percent .Also the thing is boiling out fuel,but if I unplug bank 1 harness it stops and actually runs better on just one bank. I think I have heard of people replacing and injector only to find another one pops up bad. Also, now when I run the cyl contribution test, one time it will fail cyl 5 and the next time 3 and then maybe 8. I have ohmed out all the injectors and they ohm out ok. I suppose there is one or more injectors on bank one that is causing the horrific fuel smoke. Since I have no way to kill cylinders do I just recommend more injectors?
