Well our family's f-250 developed a miss fire on cylinder 4. I decided to change the plugs figuring they could be no worse than doing them on a 3800. Boy was I wrong. First off it is coil on plug. So I have to remove each coil to get to each plug. The next great thing is you have to remove the fuel rails to get the coils off. So I have been fighting them for about 6 hours over 3 days. I finally get 7 done and have to pull it out of the garage for now so we can park our other car in the spot. Go figure that the one plug I have not done is the cylinder it is missing on. So I still do not know if it is the plugs, coils, injectors etc.. causing the misfire. So I am just pretty pissed right now and am almost ready to send the truck off to some one else to mess with and send a ratchet through a window.
