| | 02 sensor problem?
hi all i am having a problem with my swap (2006 5.3l/4l60e) into a 1974 chevy truck. I got the bosch universal o2 sensors (black, white, white, grey) and i connected the wiring using an online bosch 02 sensor page. I connected both sensors as black=purple, grey=tan, and white=dark brown, white= pink. my truck runs rich and throws codes p0172 and p0174. when i get the live data only bank 1 reads. The maf and bank 2 doesn't read at all. I disconnected both 02 sensors and the truck idles and responds well and the maf reads. Could i have done something wrong to the bank 2 sensor that would make it read/run this way? or? any help is greatly appreciated.
