Help! Car Idles Rough, Won't Accelerate, Service Engine Soon Light Flashes, Code P300

NeoNz

Hey,

So long story short, i was receiving faults and after my HFC install, already ordered new Downstream sensors to the NTK (OEM) and changed these and have been receiving these Error Codes from my BAFX Bluetooth Reader.

The code log below is from after i changed to O2 Sensors to the NTK OEM ones, Odd it is showing P0057 and P0037 now?! Heater Control Circuit Low. Does this mean those O2 sensors are bad that I just replaced?

I only received P0031 P0051 and P0150 before i swapped out the NTK Sensors. Crazy.

I will put the old stock ones back in. See if i can get it back to only P0031 P0051 and P0150. IF this is the case, do i need to change both upstream O2 sensors? Are they Shot?
