Car keeps stalling out, need help please
whats up guys, out of nowhere the car started stalling out today, Got codes 3,4...4,1....9,1...and 10,5. I was wondering if the oxygen sensor set off the rest of the codes. Any help would be appreciated. Thanks!

ok... if i understand correctly you have
0403: knock sensor code
0401: intake air temperature sensor faulty or circuit faulty.
0901: upstream O2 sensor heater circuit faulty (right bank)
1005: EGR solenoid valve or circuit fault.
So, what theses codes are telling me is you have some good chances that your EGR valve is blocked open. This can trigger other codes like 0403.
Your code 0901 is independent, the heating circuit is faulty. Perhaps the O2 sensor itself but perhaps you don't have 12V going to your O2 sensor too.
0401: If you have an aftermarket intake, be sure that the sensor is not floating somewere in the engine bay. Look if he's well connected too. Perhaps the sensor is faulty or there is a problem in the harness.
0403: Repair the EGR before changing the knock sensor.
Good luck!
