anyone have an extra laying around .. the dmch or similiar style?? one of the ends of mine was rusted for some reason and it broke so i cleaned it up and recrimped it back on but i dont think its fully working well enough and is causing the engine to not really missfire but run a little rough at idle.. the set i have is only about 2 yrs old so thats kind of irritating and i dont want to buy another set for one wire..... thanks.. .Dave..
