Didn't use any tool. Just meticulously a little pressure bit by bit. The gap was right in there with them all. Might have damaged them somewhat? Hard to say. Visual inspection and gap measurement seemed alright. Still not sure what my issue is. Random misfires jumping bank to bank. Like cyl3 then cyl5. Cyl1 then cyl7. Just chaos. Every time I put a wrench to it the truck runs worse.
