As said, verify fuel pressure and initial timing. Assure that the timing advance works.

Connect a scan tool, verify ALL the sensors, especially the knock sensor. Common for the knock sensor wiring to degrade. If the O2 sensor isn't reporting correctly, the engine may be running lean.

Is there any way to confirm the knock sensor is fully functional? I broke my single wire when replacing the starter, and ran it like that for a few days with no CEL while I waited on another pig tail. After I hooked it up, I can see knock counts on my laptop when I ran it, to verify it was working. This is pretty much the only sensor, besides the MAP, that I have not replaced. Truck still ildes rough when warm, ive gotten used to it.

Sorry OP!
