    quick question. I just re-gapped my plugs, after i found out the gap was wrong. I was wondering what a good plug would look like after being used? A photo would be great. Mine looked clean, but alittle white. Thanks

    in most repair manuals, there are pics of what plugs should look like and what they look like if something is off and what can cause this. try that if nothing else.

    if it is a little white, that just shows that the mixture is a little on the lean side. nothing major as long as you have the car adjusted for it and that it isn't too lean
