Its possible you could be running and starting off the 3x'* reference pulse instead of the 18x reference pulse...

with the codes you have I'd replace the sensor and see what you find..

Haven't had the time to swap the sensor yet, but today it kinda worried me. Most of the way through my long hot drive home, it tried to poop out. Revs dropped, popped back up, bucked, back-fired, exhaust puffed smoke, was fine for a minute, did it again, SES light came on, then again... then it stopped and I made it home. Scan showed 19 showed back up. It only shows up when the light comes on. It seems to do it more often towards the end of long hot drives.

That sounds like one of 2 possibilities... Either that crank sensor is unhappy, or the ICM is taking a ****.... Let us know what you find..

Any luck cleaning ICM, checking coils for cracks etc or using a compressor to blow any garbage off the crank sensor?

I have had no diagnosis time, other than making sure the connector was securly seated.
