also this is a dumb seeming comment, but

how are your plugs and wires?
Ive had a bad wire that i presume was internally too resistive from factory and when i Put it on, I had a cutout, miss, but more from the lack of participation of a cylinder rather than improper timing of the combustion, and found my wire , which was new, worked fine at idle but if i gave the throttle some go, it would arc out of the middle of the wire onto my engine hoist hook
ignore the random paint doodles on the engine
earlier this year i was marking fasteners that I suspected were loosening from vibration and the markers and the atmospheric conditions made a perfect scenario in which i think the paint fumes made me a little high because i ended up doing that for an hour and eventually I was like
"what the **** am i doing" and got some air.
It was a weird day.
ANyway, see the hook, my wire was closer to it and defective, it like melted the wire sleeve at the spot too, weird. See the coil end? You have a cap of course, but the idea is the same. The
nub the wire is on needs to be air tight, secured tightly to the nub on the tower, and also clean of corrosion. any
corrosion is resistance, any arcing or carbon tracking(ionization from high voltage spark jumping the gap in the closed space, etching carbon into the metal or just slowly zapping away metal) is resistance, any gap is energy spent to cross the small air space instead of conducting through the wire and cap, and that energy is
less vroom vroom from engine and it can be a situation where load/rpm it gets worse, but handles idle ok. improperly pulling wires(recommend the pliers) is great at separating the end on the wire so it becomes loose fitting. Use some dieletric grease to seal out 1) moisture 2) air. you want there to be no place for air since its displaced by the grease. which also keeps it easier to remove especially on plugs that are smooth on the porcelain. the ribs are common on our trucks, which btoh can be a bitch to pull off. Also then finally, the plug.
A bad plug doesnt let the zap zap make the vroom vroom.

I’m cereal, check those wires. Visually and if adventurous with a multi meter. Or. Here how about this. Are you able to replicate the issue at idle or low speed
