So I installed my new 1 3/4 kook headers. Had to replace the to O2 sensors before the Cat with universals until I get to the states. Now a week later the p0053 code comes up got it read and states "heated oxygen, sensor heater, resistance bank 1 , sensor 1 , confirmed, besides that it say the same on the second part except at the end it says pending. Now the issue is finding out which one is bad. Any one deal with this before?
