Bad plugs?

[v6maro]

I pulled my plugs, 1st one was whitish in color, with black soot around the threads.
2nd one was burnt orange with a white tip, black soot on threads, 3rd one burnt orange, black soot on threads.

Now, #1, why are they different, #2 what do the different colors mean?
thanks

The thing that comes into my mind when you say an orange color is the coolent. I know that if you have a leak or even a cracked block you plugs will have a tint (green, blue, orange, what ever coolent you are using) to them. If you do have a leak not all the plugs will have this coloring to them. You might want to have have that looked at.

I could be wrong but I remember reading that soot means its running somewhat rich.

BTW, have fun pulling those passenger plugs.

passenger side isn't that bad for me, only takes about 20-30m for all 3, i've done it some many times.

As for running rich, I believe thats all it is since mt A/F meter is running rich a lot, my wide o2 band on the dyno showed 9, and i am guzzling gas like crazy.

White on a plug indicates running lean.The less white the better.
