so, i need help making sense of this. i did a good job effing up one of my o2 sensors and bung( ireally dont wanna go into it). after doing so i was only running 1 o2 sensor, but i was getting a whole list of bank 1 codes, basically telling me it wasnt working at all. after getting the downpipe fixed and new 02 sensor(downstream) put in place, he cleared the codes and havent come back since. normally within a day the codes will fly again. not the case. any ideas of wtf was going on? i just want some help trying to understand this confusion

 

So what are the codes you are getting now? How did you mess up an O2 sensor?

 

i dodnt remember em all, but there was p0141, 137, and like 4 others. i screwed up the bung on my o2 bung by cross threading due to bad threads on the sensor from the other dp i had. didnt pay attention to what i was doing, and effed up both dp's. i have the stock one back on now.
