After changing two oxygen sensors on the y-pipe, my car goes from 26 mpg to 31 mpg. I drive a 92 mile one way commute every day, most of which are highway.

 

Sweet! That's good news. I'm changing all three by the end of the week. Happy happy joy joy.

 

Your signature video seems too violent to me. It would be helpful if you could get rid of it.

 

Were you getting codes?

 

I didn't get check engine llight on but got bad oxygen sensor and bad knock sensor codes. I haven't replaced the knock sensor since I haven't figure out how to do it. My car is a 1996 I30t 5 sped with every options including VLSD.

 

after changin my o2 sensors my mileage went up slightly but my car seemed to run more smoothly, but maybe its all in my head. But thats great news on the gas mileage, especially with the gas prices

 

A 5 spd might help with mileage, just woondering.

 

when do u know if you need o2 sensors when you have a 95 max that auto zone cant get codes for? my check engine light is on.

 

The Oxygen Sensor codes were founded at auutozone. I didn't know that I had bad oxygen sensors. I asked the autozone guy to check whether I got any codes while I was there buying a new battery.

 

And my car has 142K miles on it. Still running like new.

 

Well I guess at 173k, I need to be getting some new O2 sensors. But I already get about 31-33+ mpg, would it be neccesary.

 

Can someone in Louisville, KY or Cincinnati, OH area help me with changing the knock sensor?

 

I might be able to help you
PM me with some details

 

Thanks, Pieps. I will move to West Chester or Masion in 1-2 mos. Will PM you later.

 

my o2's got slow responce already at 90k.... I change it but I changed the wrong o2 in the y-pipe, now im waiting for some money to change the right one. Anyway Now im getting about 18mpg driving highway and city, however I drive hard cause I own a max and not a honda. Even last year the best I did was like 26mpg, driving like a total newb grandma, which I figure was useless cause I cannot drive like that for a full tank. Idk how you guys get over 30mpg... must be 55 cruise on highway.... but then I ask why do u own a maxima?

 

I always doing 78 Cruise. It seems that Cops will get those driving over 80 MPH>

 

I don't think you necessarily have to change the rear one, it doesn't have to do anything with mileage or performance.

 

Excuse me?

Doesn't matter, already bought three and they're going in on Friday. Along with brakes and axle's.

 

I think he means your avatar, hope you have fun working on your car!

 

I know what he means, but it was in a PG-13 movie (Dodgeball), and this is a PG-13 site, and the Sprint himself put it in there for me. Oh well.

I gotta get the car into the shop, thank god today is pay-day.

 

Can anyone help me ?!

My check engine light was on and I had it computer diagnosed.
I got error code: PO150 Bank 2 , Sensor 1.

Also my mileage now is 13 m/g in the city.

I was told it's one of the front O2 sensors.

I would like to buy the sensor on eBay but I don't know which one do I need.

I know that there are 2 sensors in the front: one on the radiator side and one near firewall side.
Are two of those front sensors the same or they are different ???
Which of the two sensors do I need ? and where can I find it on eBay ?

I looked on ebay, all sensors they sell called just "Front" or "Back" and I dont see any "Radiator side" or "Firewall side" sensors.

I have 97 Maxima GLE.

Thanks

 

:attention The 4th gen community has gone down hill.

 

I would just go ahead to replace the two O2 sensors in the y-pipe. I bought mine on oxygensensor.com
