https://stream.echo6.co/videos/watch/7679db66-d788-4ee3-a781-38ef0977395c In Part 2 we pinpoint the issue that is causing the rough surging idle on this Ford F250 5.4L V8. I show alternate methods (with and without a scan tool) that lead to the same conclusion. Towards the end of Part 2 we look at FUEL TRIMS at idle. Part 3 we will complete and verify the repair. Thanks for watching!
