Rdobbs, I'd seriously consider buying another set of plugs to replace the AC Delco's. I could post the YouTube video of the Chinese sweat shop where they have a bunch of people assembling plugs and throwing them into huge bins when "done", but suffice it to say that AC Delco's QA/QC process on spark plugs is not what it used to be. It's not at all unusual to get a bad plug in a set these days.
