Check the plugs and when you do, examine them closely to see which one looks the worst. Don't mix them up. Make sure you know which came from which cylinder. It is just my guess, but I would be thinking about a possible dirty injector on the worse plug's cylinder.

I like the platinum. I like the bigger electrode.

On the injectors, I have the luxury of sticking in a used injector that I know is good. I would certainly try a couple of tanks with the injector cleaner in it. Note by the performance and then plugs if necessary if it is improving. Then professional cleaning or replacement.

Try some injector cleaner and think about replacing the fuel filter. You may have an injector that is sticking a bit and not closing down as it is supposed to. That explains the fowling of the one plug.
