Plug Color
While I was checking my plugs last I noticed that the insulator was tan/brown on the plug wire side. Any ideas as to what may cause this?

If the last person to put the plugs in used silicon grease on the boots (a common practice to help them come off next time and seal out moisture) the grease can turn colors. If it is a chaulky/carbon like the plugs may have been "traking" that is the spark was jumping to the block instead of at the electrode (that is a WAG by the way, usally tracking happens at the cap due to cracks, but I thought I'd throw it out anyway). Was there a problem with mis-firing? That would indicate tracking.
