I knew that they have different grounding so I found the diagram and wired them up. I belive I wired them correctly but I did get them from a junk yard so they may be no good so Im just going to put what suppose to be on it
I'm getting new ACdelco ones. I know they're more expensive but I try to always by GM/ACDelco for sensors
Well got two new sensors and wired them up and it's still doing the same thing. As long as I got the two pins grounded I got WOT and throttle response. With the ground off, the throttle so bad that I have to put in low lock just so i wont stall it out so I can get it back in the shop. I dont know what else to try.

when you say you wired it, does that mean you have altered the factory wiring configuration? They should be plug and play. Also, what PCM are you using? What year tune? DBC or DBW throttle body? Have you pulled the vac line off the fuel pressure reg and started the engine to see if it's leaking fuel past the diaphram?

I Have the black rectangle harness orginally but couldnt find O2 sensor so I wired In the white square end. But now I have brand new black O2 sensor and connector thats suppose to be for my harness. I have the 0411 PCM and IDK about the tune since I let another guy of internet do it (may be my problem) with DBC throttle body and Im fixing to see if it leaking past diaphram. IM thinking that maybe the guy didnt disable all that he suppose to cuz pin 32 and 34 is a swicth for park or maybe a netural safety?

It's not leaking fuel either

The problem was the computer was looking for anti lock brake signal. The first guy I used didnt delete it out of computer. After that everything was good

Glad its working right now, but im a little confused. I haven't seen this issue before.
