So, I pulled out my spark plugs and replaced them with motorcraft platinums (I had put in motorcraft copper plugs, last time). I find they have a white powder coat on the ends, and I am sure that means something specific. But what? Here they are after I took them out (cyl 4, 3, 2, 1, 5, 6, 7 8):
I also remember an article or thread somewhere that showed what the different potential conditions of different spark plugs meant was going on.
"...means it was running rich"
"...means it was running lean"
"...means you should run a colder plug"
That kind of thing.
Anyway, help with info on what my white powder coated spark plugs might mean, or a link to a thread/article online that covers the subject, would be appreciated. I put the new ones in and my car runs great again, BTW. That was the issue with the intermittent hesitation and power loss I was having.
