1993 2.3L with codes 224 & 513

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.

Well, two for two. Oh well. It was the thought that counted.
