Me again today's issue is the car has the service engine light and when I read my cheap OEM codes it is consistent PO134 and PO135 O2 sensor.

What leads me to believe this is what it is when googling car stalling on reverse it comes up with O2 sensor. Has this happened to anyone?

Heading to my friendly Pep Boys tomorrow as I cannot bother @Mollusk again (btw he is a saint!) let me know if anyone has any thoughts on this please.

Thanks!
