Re: extended primary o2 wires now have code 63 (Civicse)
ok i just had my car diagnosed and they said its a bad o2 sensor from the code 63. new one is 236$...shitty. i just had my header and cat back installed, and extended the o2 wires. what could have caused this? i just don't want to buy a new one and have it happen again

Re: (Civicse)
shouldn't my car be running like crap with a bad o2 sensor? and with the primary unplugged the car runs fine with same gas mileage. i'm just trying to figure out why ppl keep saying the primary is so important, cause apparently its not.
