Well the other day I was going to take off my heatshield over the headers, but not knowing any better I thought that the o2 sensor just pulled straight out, so I took out the trusty vice grips and rubber hammer and went to work... well I never got it out. Then when I went to drive my car my check engine light came on, so I went back home and checked the codes: yeap it threw a oxygen sensore code...and the o2 sensor is $70, so what effects can it have on my engine if I dont get a new one and just leave the messed up sensor? Will the performance lost be worth $70? Will it have anything to do with gas mileage?
