What makes the RPM needle fall below 1. My car shuts off when I'm completely stopped

Hello and thanks for responding, I've taken it to a Toyota dealership and they couldn't find any codes. The check engine light never came on but the car still does the same thing.

Ok, test the throttle position sensor. It may have a dead spot. Also, you can put the car in neutral while driving and let the car roll without pressing the gas. See if it does then.

Yes, I've tried to put it in neutral when I would come to a red light and it still shut off on me 2 out of 5 times

Test the throttle position sensor, check the idle air control valve for carbon buildup, and make sure the EGR system is clean and sealed as well.

Ok I'll do those 3 things and keep you posted

Sounds good, I'll be here.
