Spark Plug Analysis

[FridayGt]

I know this may be old hat for a lot of you more experienced folks on here, but I figured this could help someone else here. I realize this isn't a MoPar site, but unless I'm mistaken, it should still be a good visual guide on reading your spark plugs and has helped me quite a bit. Just hoping to pass on a little fruit of my research/ reading labor. Hope this helps someone else out there.

It is amazing what some people who really know how to read spark plugs can learn from it. I'm definitely NOT one of those people.

I know what you mean, I was utterly impressed by how that guy was reading the plugs in your link. That seriously helps me out a lot though with what I've got working with my car right now. There was such a long time that I had sat there looking at plugs, both fouled and not, just utterly confused. Tweaking done with my timing that has had me wondering if I had it right down to the tenth of a degree or not. I've got both of those links bookmarked now.
