Alright, I just cold started the engine and heard the smog pump run for maybe 2-3 minutes before it cut out. I went for a drive with the AC on and got it up to operating temp, came home and checked the codes again.....just 1 blink.....could that be it? I mean it is kind of anti-climatic (in a good way), but could I be done for now?
