check engine light after header install
He guys got done installing my lg pro headers on my 08 ls3 with cats.
I installed the O2 extenders on the front two sensors and "turned off" the back two sensors (post cat) using HP tuners. Ater a couple days I'm now getting these codes
0054
0060
0140
0160
Am I having issues with my front o2 extenstions? I'm guessing by these codes that the issues are with the front two o2 extenstions? If I'm issues with the front two o2s could I be running rich or lean?
Suggestions? Thanks

your probably running rich. This is common if you dont have a tune after the header install. Im not a master tuner so I cant help you there hopefull somebody here can help you fix it.

Google is your friend... http://www.obd-codes.com/trouble_codes/
- P0054 = HO2S Heater Resistance (Bank 1, Sensor 2)
- P0060 = HO2S Heater Resistance (Bank 2, Sensor 2)
- P0140 = 02 Sensor Circuit No Activity Detected (Bank 1 Sensor 2)
- P0160 = 02 Sensor Circuit No Activity Detected (Bank 2 Sensor 2)
Bank 1 = Driver's Side, Bank 2 = Passenger Side, Sensor 1 = Pre-Cat Oxygen Sensor, Sensor 2 = Rear 02 sensors. You need to go back into HP Tuners and look for anything that says "Sensor 2" and turn it off...you missed a few.
