I went to get my car inspected ages ago and they said it wouldnt pass because of some 02 sensor misfiring.he just gave me 60 day fail sticker to get it done, said it didnt say it was bad, just not heating up correctly?.. i just went to get it done, he removed the 02 sensor, and put it back on and said it wasnt misfiring again, and gave me a sticker so we are all set. i leave the shop, in under 30seconds of driving the CL light comes right back on with the same issue. Does this need to be replaced?it was just replaced in july which doesnt make sense to me.
