99 Ford F250 5.4L: Surging/Rough Idle Case Study -Part 2

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!
