You guys having issues with the plugs arcing where the nut meets the porcelain? The eforst time I thought it was the wires, changed the plugs and wires. I have a slight miss again, and it's doing the same thing. At light I can see blue sparks about where the nut meets the porcelain on the spark plugs. Thinking about trying ngk plugs. This is the second set of delcos in 5,000 miles.
