Op what fuel are you running? Any chance you have put leaded fuel through the car or e85?

Edit.. just saw you are getting heater codes. That has nothing to do with the flow of exhaust across the sensor. That is simply a heater that warms the sensor up to operating temperature.
The car is currently on e85 but all the problems were consistent before the switch. If my codes arent related to the flow how would i go about fixing it. Cant find much on the heater sensor. Ive never had one fo put before the other so it might be a fuse? Not sure what else it would be
