Bad idle fuel system open loop?

Hey guys..

I have been having some issues with my car for the last little while.. I replaced the ICV, DISA, throttle body (with a used unit).. When I replaced the throttle body the car ran great for a week or so (then I left town and when I came back it was running fine then all of a sudden the issue popped up again)..

Seems like when I am on the throttle hard it runs fine but then when I decelerate I get EML + traction control and I have 0 power.. Idle sometimes will hold steady but when I touch the throttle the RPMs dip.. Once it revs above 2-3k it shoots right up and revs fine.. The car is not driveable the way it is.. I started monitoring everything and noticed that when the idle is steady and running ok the fuel system status shows Closed loop, using Ho2 sensors.. As soon as the idle goes out of wack the fuel system status shows open loop, fault on both fuel systems (it shows two different banks)..

My car is supercharged with an AA stage 2 blower.. I replaced the fuel pump and filter over the last week and issues still appear to be the same..

Does anyone have any ideas or suggestions? The faults show lean fuel in bank 1 and 2 as well as ICV stuck open..

Thanks guys
