Yesterday as i was driving home from work i noticed my check engine light come on. So i stopped at advanced auto parts to read the code. I'm assuming its either the coils or the plugs. The truck has 62k miles on and i'm not sure if they've ever been replaced because i bought the truck used. I also put a cherry bomb muffler on it last week (idk if that would effect it) Any help would be greatly appreciated.
