WOW! Thank you, Bill! That anomaly escaped me completely.

Here's another weird thing about it....which may be related to the internal clock thing: The idle is fast. It has a warm idle of around 800 give or take based on the tachometer (since no data) but when a functionally good PCM is in it, it's normal. When a minute isn't quite a minute, this would make sense.

The guy isn't worried about it as it's a worn-out ranch pickup. I just wanted to do some computer-based diagnostics on it even though it was an obvious injector issue once all mechanical possibilities were ruled out.
