2007 4.3L misfire when idling but not so much when driving
I have a 2007 Ford Expedition with 5.4L 3v. I have had P0340 and P0344 codes for some time. At that time it would run rough at idle but not when driving. A little while back it started misfiring on 03 primarily when idling . The spark plug was swapped , coil checked and it still does it...- 07FORDEXPEDITION
