It was a shifty looking figure, almost manlike but kept avoiding my calls out to it. I think it might have been...

Put new ones in this weekend to try and solve my misfire at WOT, stock engine no mods. All seemed to be about .038-.042. Two on drivers side had some carbon buildup theres pics in the shuddering thread. Too early to tell if it made anything better, but seems to accelerate a little smoother. I gapped new ones about .032. Pretty easy to do but slammed my hands a couple times once the drivers side coils let loose.

one hour and one busted knuckle later the truck seems to run a little smoother at idle and driving seems about the same, BAD *** just like before. all but one spark plug was at .040 the one was about .035, dropped them all to .034 will see with time how it goes. the blowoff valve mod was staring at me the entire time. I just need to get all the parts together first.

I pulled all mine last night and every one were at .41. I regapped em down to .33 so we see. Haven't had any issues yet but figured worth checking.
