just took it to the dealership, and at first they were hesistant to take it in as i didnt have an "appointment"
kept saying that it looks fine as no current lights are on the dash.. i told them to just scan it, they finally agreed and came back to me saying "oh you were right.. theres a misfire on a couple occasions in cylinder 5.. we'll have to check to see if its the coil/plug or something else". good thing is its covered under CPO, just waiting for them to come back to me, should i ask them to change out all the coils and plugs if i pay for the parts?
