Re: What if i dont change my O2 sensor??? (Blaze45)
If you dont have an o2 sensor working properly then you are never going to have the correct A/F ratio. I believe if there is no signal at all the ECU puts it into limp mode and it runs very rich to prevent a lean condtion. This means you'll get horrible fuel mileage and you'll have to clean up your spark plugs when you do get around to replacing it. Last time I replaced one I used a Bosch universal and just soldered on the plug from my last one, I think the total was $42.00 at autozone.
