OK, further observations. I found that my ICM faults out only after heating up and only after a restart. SOOOO if I go out and do the at home ICM test bright and early after an overnight sit, it will test fine. But then I noticed that the right bank of the primary coil craps out after warm up and after restart. As an experiment I tried something. I loosened the ICM screws, slipped two hardwood shims under the ICM to create and airspace. I also have a ground wire running from the ground screw to the engine. After a long hot drive the coil is still firing on all cylinders. I realize this is a quick fix for a failing ICM, but it is an interesting experiment eh?
