I've read in different pieces of (ford) literature and i've read in different places on this board about the 'best' spark plug to use and i keep hearing some people say 32PP is the best, and other people say that the 34PP is the best. What are the differences, pro's and con's of each plug...anybody? Might have to change mine....AGAIN cuz i have a misfire that is TICKING ME OFF! , but i wanna chose the 'right' plug..(if there is one). thanx
