In fact, you should make sure you have the o2 feedback set to 100 while adjusting your K value to get your 14.7 cruise. Get a new o2 sensor, or fix your wiring.

Alright I'll try do that today, but what's curious to me is how come the car was drivable? When I either had it connected or disconnected? Like even 2 months ago before I fixed my bogging it was idling fine, my afr was perfect, and the only issue was that it would bog when coming to a stop. That was due to my tps being way off and staying a bit open my idle screw slammed so low. I couldn't adjust my to go past 900. After I adjusted my tps, the car would just die completely when I would start it, after I gave it some gas and let my dad bring up the idle screw it was idling like a dream even without the o2 sensor.

Now two weeks later it's running like completely shit...
I'll check out the thing in NDS, hopefully it's that.
