              AFAIK, you risk messing up your cats if you drive with a misfire.

                  Swap the cop with #6. if the misfire moves... the cop is the problem. might check the plug too while you're in there. If the plug is ok and the ceramic portion doesn't spin (should be tight), just put it back, otherwise clean/replace as needed. If after all of that, the misfire stays on #7, injector, or compression/valves.

                    It's a very inconsistent miss. Comes and goes

                      If I unplug the injector should be ok to drive temp as no fuel will go to that cylinder to be dumped in the cats

                        If you unplug that injector... it probably won't idle very well at all if it does. It'll drive even worse.

                              Also, when my coil went out, I didn't get a misfire code. When a spark plug went out, I did get a misfire code. It seriously could just be the f'n plug.
