could possibly be a broken valve spring or valve not seating properly. we have had a few engines (at my workshop) with the same problems that you are complaining of, after doing all the stuff you have (leads, plugs), the engine still ran like crap.
pulled the rocker cover off, only to find a valve spring broken and not allowing air into cylinder.....
suggest compression test on all cylinders and comparing no.6 with others.
also if you get injectors out, swap no.6 with another cylinder and see if misfire moves to other cylinder, then you will know for sure its the injector
