I went ahead and replaced the ASD relay with a new one from the dealer and re-did all the connections to it with new connectors and crimped with a proper wire crimping tool. If I shake the ASD relay wiring that no longer causes the van to stall. Also found a loose connection of a wire coming out of the base of the distributor. This helped the engine run a lot smoother, and it no longer stalls.
BUT… the dumb thing still misses occasionally at about 50 mph or faster. won’t miss at idle, purrs like a kitten. So I have done what I can and the van is now in ths shop.
