Changing O2 sensor(s)
I'm troubleshooting poor gas mileage & rough idle. I'm thinking of changing the O2 sensors. No CEL lights, codes or anything else. I've had a cople people recommend trying it. How hard is it to change them (pre-cat). I can see both and reach one, but can't find where the wiring goes on oone and can barely touch the end of the other (driver side)
Let me be more specific. Is there a trick to changing them? Looks like the passenger side would be easier accessed through the wheel well. Or if anyone would have a better suggestion to try first, I'm open, especially changing both sensors is $100 I'd rather not have to spend unless necessary.
