I have a 97 5.4L Expedition Eddie Bauer 106k mikes P306 code. We have had plugs replaced and a new coil on #6 cylinder. The code came back. Mechanic said it probably was a dirty injector he power flushed system with sea foam. Still skipped then they installed new injector. Ran OK for a short while then started skipping and code came back. It always seems to be after a bad bump in the road. Where does the power to the coil come from and can it be a bad wire to the coil?
