Help me out guys.. PO172 - System to rich Bank1, PO175 - System to rich Bank2, and PO101 - Mass or Volume air flow, circuit range performance problem. Right now even though the check Engine light is on the car is running fine. I recently replaced the Oxy. sensors for the the front (both). Someone told me with the PO101 code if it was the air flow sensor the car would be stalling. How true I don't know. Any help guys....
Thanks
