Car: 2000 Camaro SS Auto

I recently did a LT header install on my SS with Pacesetter LT's, ORY, and SLP LM1. I installed O2 simms in the place of the rear o2 sensors and left the stock O2 sensors up front, I got a check engine light after about a week and just found out today what the codes are. Codes are as follows P0155 O2 Sensor Heater Circuit Malfunction (Bank 2 Sensor 1) there were 2 of those codes and that's all. My car seems to be running rich, i'm guzzling gas like no other, I probably need a tune but do you all have any suggestions on how to completely eliminate these codes and not have to keep using a scanner

I am throwing the same code. I think one of your front O2 sensors is going out. How many miles are on your car? There is a way to delete them with tuning but if you dont have a local tuner that can tune your car or if you do not own tuning software i dont suggest you delete the front O2 sensors. Well goodluck.

93k on the car ( clean as a whistle tho ), one of my front O2's was really grimey looking... do you know if I can use the rears for the front?

Get rid of the o2 extensions. Get some C5 rear o2s. They have a long connector plug and are calibrated to work further down stream where the exhaust is not as hot.

your passenger side front 02 sensor's heater circuit is gone. just replace o2 sensor

Thanks that sensor was rather nasty looking so I think I will. I hope it fixes the mileage issue...do you think it will?
