Gen5 Camaro SS with S/C, unstable idle and weird Ltft

[shinysun]

I checked every hardware, but couldn't solve it.

Idle is jumpy and bank1,2 ltfts are weird.

I tried to exchanged the injectors, spark plugs, wires ,coils and o2 sensors on bank1 and 2, but the situation is the same.

and tried to get a new MAF , MAP and throttle. and also checked leaks, but no signs.

What should I need to check?

I attached the scanner file for it.

maybe an exhaust leak in bank 2? i see you have the pids for a wb, which bank is it installed in?

For checking , I put sensors on each bank. 15.0 afr on bank 1 and 12.5 on bank2

Probably a faulty sensor , get a new one and check .

I got the new one, but nothing changed.

Im still thinking an exhaust leak at the head or something.
