Wierd Spark Plug Question
I did a tune up iver the weekend and changed my champion spark plugs to the NGK plugs and notice two of the plugs I removed, one from piston 1 and the other from #4 were barely worn down versus the other four were pretty worn down. What's the diagnosis for that?

Oh srry I should have elaborated a little more. I changed them about 32k miles ago. About two winters ago figured it was time to do it again. Four spark plugs electrodes where pretty worn to a point that it was close to time for a swap. Two of them hardly looked like they were worn at all. All spark plugs showed normal operation when looking at a spark plug diagnosis diagram. So is there anything to worry about....should I be concerned that two pistons are not operateing the same as the other four or are the other four the problem that they were worn down more than the other two.
