what exactly was the condition of the plugs? then you can get better help. if possible take pictures of your plugs

looks to be some oil stain discoloration around the hex part of the plug. Was there any oil in the spark plug cavities? As mentioned above, this will most certainly cause major misfiring and eventually short out a coil pack. if the miss is there at idle, you can start disconnecting one coil pack at a time and sense for a change in idle quality. whichever coil you disconnect and there is no change, that could be your culprit. Sounds to me as if you do maybe have some oil that was in the plug holes. This would explain why after a long 125 mile drive, it developed the miss again. If there was any oil in the holes I'd replace the valve cover gaskets, clean the holes out really well, clean any oil out of the spark plug boots and then test drive it.

in addition to the oil on the hex part, what do the electrodes look like? (hard to tell from the pics)
if it's black and sooty you are running rich, which can be caused by intake leaks. have any fault codes come up?
