Just a friendly reminder....
...to change your O2 sensor. It should be done about every two years and damn does it make a difference when you do!
Just did mine today. I forgot what an extremely stable idle and no reduced timing during warm-up is like. Plus, the extra 2 MPG really helps

I disagree.
Our cars barely even read our O2 sensors. In fact, if you just unplug your sensor and go driving, it will probably take about 5-6 minutes before your CEL even comes on.
I've never changed mine, so it's at least 9 years and 90k miles old, if not older, and I STILL get 26-27mpg.
What little MPG you may gain won't be near enough to recoup the cost of all those sensors.

Hmmm well I paid $40 for a Bosch universal O2 sensor and wired it in. Immediately after installing it,I noticed that I no longer have any idling issues (it used to hunt for the correct idle RPM), it doesn't pull timing when I'm driving and the engine is still a little cold and I'm getting an extra 2 MPG.
So while you may not have noticed anything, I certainly did. It may be due to the fact that I'm using the Revtronix chip, so maybe they've designed their chip to read the O2 sensor more often.

Well you should change it, maybe you won't recoup the money in fuel, but you will with how long the engine lasts, because it runs better with the sensor. Most cars will run fine without it, but it's always better with it. 2 years seems like far too often though, they don't go bad that fast unless you have other problems.
Plus a properly functioning O2 sensor will extend the life of your catalytic converter. rich running engines cause the cat to be get hotter and wear out faster. Probably more important than an O2 sensor though is to have a sealed exhaust system, especially before the sensor since a simple air leak can wreak more havoc than an old sensor.

Oh that's me, the jerking I mean, I should check my records and see if it's been changed. I need to find my tiny vacuum leak first though...HappyFrog wrote:Error code 32 or if the car jerks when accelerating from the lower rev range.speedmaxx wrote:how can I tell if my 02 is acually bad? my idle is perfect, perfromance is good, mpg is also good.
