UPDATE** Ran some tests this morning. Coils are in spec but the exhaust side 1-4 is not getting the switching signal from the ICM. Will be shopping for a new Ignition Control Module soon.
The INTAKE side is not the problem. As I said above it is the 1-4 side of the REAR coil that fires the EXHAUST side. Truck was running at idle and the 2-3 side of that coil was firing fine.
