not to shure but i was having a bad part throttle miss ,found out it was the gap on my plugs was like .0028 so i put it to .0040 runs like a champ but a few poeple said i can go to .0045 just was wounding what u all thought

Keep opening it up until you get a miss. It is possible to go as high as .060 or so. A wider plug gap will give a much nicer idle quality too.
