Here a tricky situation. when the ECM set a injector code, and it is not that injector of that cylinder it set. . This one you would need to go according to the firing order, . It would be the one previous to the next firing order , what happens you can get a fuel injector code of a particular cylinder, and it is not that cylinder fuel injector it is the one previuos to its firing order. that injector would short and would take power from it next injector. If this is not resolved soon it would definetly take out its injector driver in the ECM
