Can you allow the engine to idle without the O2 sensor connected for long enough to get the engine up to operating temperature, then reconnect the O2 sensor, erase those two codes, and start it back up to see if it will then idle properly using the O2 sensor data at normal operating temp?
And to ask again, are all of your sensors OEM, or are any aftermarket sensors installed?

I'll try that today. I believe the IAT sensor is in the MAF sensor and the MAF is brand new OEM.
I also have purchased another OEM upstream 02 sensor but might return it i dont believe the 02 is the issue. Engine just wants to run lean even with throttle.
I actually drove it a short distance but barely any throttle input. I didnt notice til today when i looked it seems to have alot of knocking signal.

No, all my sensors are OEM except for the coolant temp sensor. It is an aftermarket one but i don't believe it to be the issue. It is brand new but i can always switch back to the OEM coolant temp sensor.
