Saw this thing blow up yesterday. I've had a few questions go unanswered on here over the years, but eventually just found a way to get it done so I could move forward. Never complained about it, because it never does any good. Some of the questions got answered at a later date, but at that point the truck was already back on the road. No harm, no foul, people have lives to live and are not glued to their computers and this forum. Can it be frustrating? Yes. Is it worth having a fit over? Absolutely not!
Should you replace the plugs? Yes. If you have money for an 18 pack, buy the plugs instead.
