Sup dude. The code said LOC#1. The o2 sensor the used to go on the catalytic converter is the one that was moved. Right now the o2 sensor sits right before the catalytic converter. I think that before, it went right into the stock one, but since i put the free flow in, they welded the o2 sensor right before the cat. Honestly i dont know why im throwing a code. I have an extra sensor so i was thinking about switching it out to see if that was the problem. Ill tell you this, we reset the engine code, and it will throw the check engine light every 30-35 miles. Everytime i throw the code i reset the mileage just to see if there was any kind of pattern. Thanks
