HELP!! P0281 code!
zero issues before yesterday got on it hard to pass on a 2 lane.
started runnin rough got the code P0281 cleared it, checked the FICM running and got 48V, KOER test was clear.
it starts just fine cold, just as fast as usual and sounds fine till it fires then hear the missfire but not blowing smoke white or black.
should i dive in and replace the injector or could it be something else?
