Its definatly the spark plugs causing it to misfire. I went down the bypass earlier and at about 3k it starts misfiring and isnt a happy bunny. I thought it was only happening in 3rd gear but i accelerated slowly in every gear and theyre all the same.

It has NGK PFR6B's at the moment but im replacing with NGK PFR7B's. Should give a better spark and theyre recommended for modified anyway.

Im gonna start it up when it gets dark and check the leads for any sparks etc to be on the safe side.

No sparks from around the leads so pretty sure its the plugs.
