Pulled codes?! Something's wrong...Help?
Hi, I just discovered my oxygen sensor on my '88 351W was broke and the wire wasn't hooked up. THe strange thing is, this didn't show up on the computer when I pulled the codes. How much could this help gas mileage?

Really? When mine went out the first thing it did was turn on my check engine light. I would replace it because in order for the computer to adjust things correctly it needs to have the o2 sensor.
