Erratic idle with DTC of 36 or 24x signal circuit error #1

Car is idling erratically and am receiving a DTC of 36 or "24x signal circuit error " and am curious as if anyone has had the same experience, and what you did to solve this problem.. Being somewhat inexperience in this area and the Camaro book on the 3.4L engine electronics are a little ambiguous, I could use some help.

Been having a lot of wiring problems this year and am slowly rebuilding the main engine harness, essentially out of necessity. Am beginning to wonder if I should replace the whole main engine wiring harness. This harness I have now is getting old and was made from an old Camaro harness. Can anybody give me any feedback on the new harness from BMC that Brian is making?

The sensor takes an hour or so to replace but the engine can be run without for test purposes.

Yea as per Brian, check the O2 sensors.

Brian harness is ideal for the install of the V6.

I have a harness from Brian. I am installing a 3.4 in my GT with FI. I am also installing all new sensors, new injectors and oversize throttle body. Mainly to avoid any issues in the future.

Don't be apprehensive to purchase Brian's FI harness.

It is our attitude that will determine the outcome
