Driving the mgf car developed a miss fire put in new plugs still hapening what could cause this? Ive been told coil pack can play up and cause miss fire leads ok but new set on order compression seams ok could being a vvc the crank sensor playing up? Or could I have burnt out a valve?

Do the leads and coil and let me know what this does to the misfire, also check for any vacuum leaks as well.
