Powerstroke help

The oil was black as night and I changed that today, but it was just oil, and the antifreeze is just that. All the harnesses and plugs seem to be in good condition, and I haven't checked pressure at the pump yet. The way I singled out 6 and 8 was to unplug the plugs that go into the valve cover 1 at a time. When either on the driverside were unplugged, and the front on the pass side there was an obvious change in the idle. When I unplugged the rear plug on the pass side nothing changed. Then when I unhooked each injector (6 or 8) the idle didn't change much, if any at all for either one....so 2 bad injectors, or bad harness????
