I HAVE CHANGED OUT THE FUEL INJECTOR, COIL, SPARK PLUG WIRE AND SPARK PLUG. STILL GETTING CODE P0306 ND STILL RUNNING ROUGH. WHAT IS WRONG?

It would help if we knew what make, model, year and engine size. After replacing these parts, the next thing to do is check compression of that cylinder.

If the misfire is mostly at idle, check for the intake gasket leaking vacuum. Also check compression on #6.
