I missed that injectors weren't part of the test equation yet. When i was chasing a random misfire on wife's car i ran Lucas injector cleaner and it was cured. If you haven't run injector cleaner through that'd be the next thing to try also swap inevitable l injector location.

(We swapped injectors on the f150 before the crank sensor error stayed on cyl 1)
