23 - Air charge voltage high/low detected.
37 - Part throttle unlock(PTU) circuit, open or short detected.
Never ran into code 37 but it isn't going to be related to stalling. Will the engine stay running if you hold the accelerator pedal down 1/4"? Was the battery disconnected or run dead recently?
The intake air temperature sensor has an extremely low failure rate because it has only one component inside. Almost all codes related to it are due to wiring problems, most commonly stretched or corroded connector terminals.
