Car stalls turning and or going slow

Hi I have a big issue. My 08g35 stalls while turning or driving slow like though a parking lot. It’s always less the. Like 20mph and it seems like it happens after giving it some gas at least in the parking lots. The rpms dip so low for a second it just stalls out. Many times they dip but it doesn’t stall. It’s haplened a few times on the actual road which isn’t good and it was while I was making a turn with no foot on the gas. The call will continue to keep going until it actually stops so it doesn’t just stop dead after stalling. It happens like once or twice a day and I drive a lot. Another few times a day at least where it dips but doesn’t stall. Anyone have any idea what this may be?

Power steering pressure switch, PSPS is supposed so send a scaling signal back to the ECU based on the actual pressure exerted by the pump during turning and the ECU raises idle speed to compensate for the extra drag. Usually when the switch fails it's stuck open and no longer closes properly causing the engine rpms to fluctuate when the steering wheel is turned.

Verify this by turning the wheels without moving, does the idle drop or the engine stall?if yes then the signal isn't making it to the ECU, if it's an open or shorted connection then there will be a DTC engine code associated with it, if no service engine light and no code then it's usually a stuck sensor.

Easy fix, unbolt the old, bolt in the new.
