here is what i am seeing:

1 Long Light, pause, 3 longer blinks, followed by 3 short blinks.

Now is the first long blink a code? or the initial start up check engine light?

If I am reading correctly, I have a oxygen sensor (1), and a knock sensor (23).

This is only if the 1st long light is just the check engine light coming on for normal start up.

If it is not, then that would make it 33 and there is no code for 33. So I am assuming it is 1, and 23.

 

sounds good to me
