check engine light
hey guys, this weekend i had lg streets installed. i already had a hurricane intake and corsa pace car. i drove the car for about 150 miles and then the check engine light came on. im not sure if its the O2 sensors or if the car is running lean, or anything else. i was wondering if anyone else had this problem and what i should do.
thanks,
tyler

i put the lg streets on my 02 automatic. check engine light came on. i checked it with the diablo sport predditor. showed my 02 sensors. i cleared them but they just come back on after 20 mins of driving. if you went with the cat delete you need to get the codes removed with an ls-1 edit from a shop that has that. i just left it alone and drive with my check engine light for now

They can be 'tuned out' if you know someone with the software, or take your car to a local tuner and have them do it.

While I'm thinking about it: Did you move the rear O2 Sensors to the front, or did you replace the front O2's and keep the rears in place?
It's all in the paperwork you should have received with the headers: The stock O2 sensors will lose heat from their mounting position compared to the stock manifold, and therefore need a more robust heater like the ones found in the rear style O2 sensors.
When I did my car, I removed all of the O2 sensors, and then installed new 'rear style' O2's in the front locations. I get two codes because of this:
P0140 Heated Oxygen Sensor (HO2S) Circuit Insufficient Activity Bank 1 Sensor 2
P0160 Heated Oxygen Sensor (HO2S) Circuit Insufficient Activity Bank 2 Sensor 2
This is because the computer doesn't 'see' any activity on the rear O2's. This is the part that can be tuned out.
Good luck.
