Hi, I have a 2004 Expedition Eddie Bauer with the 5.4. It started like a jumping a couple of months ago and I started doing research and believed it to be the coil packs. I ordered all new coil packs installed them and it runs worse than it did. It was only doing it while in gear now it does it while idling. I unplugged each pack one at a time and checked the injectors as well and the idle got worse as I unplugged all but one and that was #8 pack. I changed it out with one of the old coils and now it only does it while in gear. This doesnt make any since to me. Anyone got any ideas thanks
