o2 issues Yeah we've all seen it, bank 2 sensor 1 slow response. Here's the rub, 3 different sensors same code. 2 GM sensors and then I swapped the crappy bosch from the driver side.
Same result, what am I missing here?
Headers, Y pipe. air pump and egr delete. otherwise all stock.

I kept throwing O2 codes after installing long tubes, so I just tuned the warning light off. I have verified that they are in the right operating range with my scanner and that my AFR is correct with a wideband.
Could be due to the headers and you'll need to find a way to make sure that the 02 sensor is sending the proper signal to the computer. I've seen videos of people taking an O2 and wiring in a resistor in order to trick the computer. Also if you know a tuner then you could have them set the rear O2's to not report.
