[QUOTE="saratoga2011, post: 1280171, member: 28409"] This is an old thread but thought I'd check to see if this fixed your problem for good. I've got a 13 6.2 super duty with 85k and I'm having the exact same issue you did. Found this thread by accident when trying to search for similar issues and yours was the only one I came across. I heard a faint ticktick.....tickticktick.....tickticktickticktick when walking by the driver's side with the truck running one day and sure enough, saw where the lower plug on #6 was arcing like it had a bad wire or damaged boot. I replaced the wires, and it still kept arcing around the plug. Swapped wires with its neighbor and it still does it. Now I'm at the point where I suspect it's either a bad coil or a bad plug and will be changing both. Not super impressed with Motorcraft SP526 plugs to begin with and your pics confirm it. I changed them at 80k and one of the factory lower plugs broke at the weld where it appeared to be rusted and hanging on by a thread...I got it out with a bolt extractor but still, I'm in FL and this truck has never seen salt or winter roads.
