I have a 2002 Superduty with 101.000 miles, I just had the recalls done at the dealer (cmp and speed controler)and now I have twice gotten P0308 code. Cylinder 8 misfire, I never take the truck to the dealer, I don't have much faith in them! I do my own work if I can. I am hoping someone can give me some ideas what I should try, or at least point me in the right direction!
Thanks
