need a solution to this CEL problem.
so i have a CEL. Im pretty sure its coming from my Berks HFC. I had it on for little over a year, and then it suddenly came on couple months back. here is my theory on the problem.
I took it to autozone, got codes P0420 and P0430. these codes mean the rear oxygen sensors( the one on the HFC) are reading the exhaust air similiar to the air before the HFC(the ones on the headers i think). Converters are suppose to "clean the air" and provide different wave lengths between the two O2 sensors. i checked the headers, intakes, exhaust, and found no leaks or anything abnormal. what can i do to get rid of the light?
what im thinking of doing:
either buying new oxygen sensors for the rear or do a ecu tune. will either of these work to get rid of the CEL.
which, specifically, ecu tune would help the most----the bully dog, technosquare reflash, cobb, etc. thanks

here is a ?: it says to disconnect the negative terminal, which i assume to reset the codes etc. I always thought it was the positive terminal? or it doesnt matter which one?
the two extenders will apply to the rear o2 sensors. i dont believe it applies to the front.

I have the same situation, got codes P0420 and P0430 and i reset them with the bully dog. I been using FI HFCs for some time now and mine has the antifoulers. That started to happen after the bullydog reflash. Also when I pressed the start button and the car is cold, it stops and need to press the button again with the gas pedal on it.

reason being - you ever notice the little spark that occurs when removing cables? if you remove the positive first , that voltage will have to travel through sensitive electrical components in order to find its ground. possibly frying everything in its path.
if this is done on the ground side, no damage to electronics will occur.
ALWAYS disconnect the negative first, and reconnect it last.
