Code 27
So i finally got the HG repair all sewn up and went to start it, wouldn't start, would maybe stumble for a few repetitions, then die.
Its throwing a code 27.
Sub Heated Oxygen Sensor Signal?
Anyone have any idea what's causing this?

Yeah? OH .
They're both plugged in and both functional. Switched them with another 95 4runner that I just replaced crank bearings on and got running like a week ago.
Sooo any ideas as to why they might be throwing a code?

Did you replace the front with a new O2 sensor? Did you test the O2 sensors that you threw in to verify they are functioning correctly? If you are sure the O2's are in good standing test the ECM/ECU.
