Message: [QUOTE="integritymechanicsbydavid, post: 1567042, member: 38890"] Posted on a different forum and no one answered. I’ve got an 08 F250 with a 6.4L. Cold start just started a slight random misfire that I can’t pin down to a cylinder. I replaced all the injectors because I had 4 out of spec. I replaced the crank and cam sensor. No luck. After the engine reached optimal temp the misfire is gone. I’ve ran live data and watched the fuel trim and I’ve done power balance and shut each cylinder off one at a time and the misfire never stopped no matter which cylinder injector was deactivated. I’m at my wits end and really could some help here. The truck is deleted and tuned. The heads are studded. Under the valve covers looks brand new. Oil is fresh. New lift pump. New injectors. Thanks for any help. [/QUOTE]
