Forget The O2 Sensor!!!!!!!!!

[Schrade]

WAY BAD CALL 94JIMMY!!!
A finely tuned motor does NOT even use the O2 sensor. A finely tuned motor uses all of the O2 which gets burned in the combustion process, and the O2 sensor does no work. A poorly tuned motor lets O2 get through the combustion process (by not burning it all), and into the exhaust, and the O2 sensor tells the ECM that compensation is necessary to fix another problem. If you'd like to see that in print, I'll be happy to get it to you. A bad O2 sensor is an extremely common myth!!!

And......what exactly is your point/reason for posting this?

I agree too many people assume the "bad O2 sensor theory" when thier car messes up on them. So, if you just felt like making a new post just 'cause, I think it would be benificial to educate people on this. I don't don't know the technical and scientific aspects of it all, but do know too many perfectly good O2 sensors get replaced every day. So it would be cool if you can elaborate on this topic so there is a point for this topic to be posted. It's always good to be educated on new things.

Looks like cadillakin' knows what's up with the bad O2 myth.

Runnin' rough? Check the O2 sensor.

Headliner fallin' down? Check the O2 sensor.

Hangnail? Check the O2 sensor.

See it/hear it all too often. Check the O2 sensor!!!

How to upload the article mods???

I'd like to see a motor that burns 100% of the Oxygen in the combustion chamber. O2 sensors compare oxygen in the exhaust stream to outside air. They are one of the most important sensors for determining fuel ratios. I agree that the fellas at autozone love to sell them anytime they see a lean bank 1 code on their scanner but to say that the O2 sensor does no work is complete BS.

I just realized this original post was 2 years old.

Yes, please check the date before posting. I'm surprised it wasn't a "newbie" that resurrected it a sit usually is one that does.
