Problem continues and gets worse at WOT it's not some little air leak.
I didn't notice there were consistent codes for cylinders 4 and 1. The waste-spark system is a series circuit-- like Christmas tree lights-- a problem with any one part will shut down the whole thing, that is both cylinders attached to that coil.
Ohm tests of ignition parts are so universally prone to false negative (test says a part is good though it is actually bad) that they really should not be in service manuals.
