2000 Sable LS idles too low at cold engine starts, and will die if the RPMs' aren't maintained above 1000 for the first minute or so. Once warmed up, it seems to idle fine most of the time (around 700 RPM). There are times though, during colder weather, that the engine will stall when sitting idle-- like waiting in line at a drive through. Could this be the Idle Air Control valve, or is it likely something else? The only codes being thrown are for the bank 2 O2 sensors.

The IAC module is located on the throttle body your best bet for a good look is to look for the part online and find it.

Same for the coolant temp sensor, I dont know where it is offhand on your vehicle, and I cant seem to find it in my diagrams, will look more, try near the upper radiator hose where it meats the engine and the side of the engine, could also be on the side of the engine block.
