The plugs out of spec was cylinder 8 (passenger rear). I could be wrong on that cylinder number, but it was passenger rear.Which plugs was that?
Ahh gotcha. I replaced them with the stock motorcraft plugs (SP548). After doing more research, I will probably go the route HB did and go one level colder when I swap them next year. I still have a stock tune, so at least there is one less variable in there to play with.@WItoTX No, I was asking what plugs did you use to fix the stumble you had.
