Your code list is incorrect on this one, I think. KOEO 341 is normally supposed to indicate that octane adjust pin circuit is open. Properly diagnosed, you would go through the octane adjust circuit (get wiring diagram) until you find the break.
That said, I suspect that the engine was pinging (a common complaint on these engines) and someone removed the octane adjust shorting bar (removed, engine timing is retarded a little bit) to try to fix it. There are better fixes for engine ping if this is the case. It's been discussed many times; see what you can find using the search function.
