doing your own tune up

this thread is great i know have heaps more stuff to do to help my vs run smoothly :} i do have a question though. it has been misfiring quite a bit especially when you floor it. i am goin to change the spark plugs and spark plug leads will this reduce the misfiring if not what else can i do to reduce the misfire

You should try to completely fix the misfire, not just reduce it.Id try replacing the plugs and leads.If it still misfires then,renew the 3 coils,use genuine holden coils or a good brand like MSD.Another thing to look out for is that you can test these coils on a multimeter,and they can show that they are still ok and within specs,but then can still cause misfiring.Ive seen it happen a couple of times now with these coils.
