How bad can a bad O2 sensor affect performance???

[micksf22accord]

i'm surprised you didn't know that, or your buddies from Dynamic Performance couldn't help you. an O2 sensor, is highly essential in making a car run its best. why do you think tuners prefer the wideband O2 when dynotuning.. coz it helps obtain a proper air/fuel ratio for optimal performance gains.

umm yeah shawnee? you smokin somethin? i want some!!


lol shawnee you build motors i know you know this shit jus slip your mind?

[Clueless]

how can u tell when its crap? is there a time table in replacing?

my car has 85k and i dont think the o2 was ever changed..

thanks.

I have 208,000miles and mine is fine, as far as I know it's never been changed.

It can also mess up your catalytic converter by running rich too.

A ServiceNews from Honda says that a "lazy" O2 sensor can cause hesitation during light acceleration. I replaced mine and I noticed an improvement. All I hear about Bosch is BAD BAD BAD!! I would buy OEM...

My dad's 90 EX 5spd had the 02 sensor go out. Gas mileage when down to like 26 mpg on the highway, now that it's fixed it gets 33-35 mpg.

Sluggish acceleration, sometimes it'd hesitate. I first replaced the 02 sensor with a Bosch OEM type (~$65) and that went bad in 3 weeks. I then replaced with Honda OEM - NGK sensor (~$150) and it's been fine since. It's been running fine for about 10,000 miles or 5 months.

not till i buy my new header and 02 sensor...
lol..

[starchland]

it can affect it pretty badly, i had a failing o2 sensor, everytime i went more than 50% throttle, it basically choked the engine.

[Clueless]

anyway to ghetto rig it back together?

well check this, i have a busted downpipe so i think it is getting to much air and reading lean, white smoke, this blows, now i dont wanna drive...

Hey as far as an o2 sensor it will mess with your timing some and make youre car smell like straiht gas because the 02 doesnt know when to add more air or fuel so it goes into limp mode. Limp mode is the worse my boys civic sounds and smells like straight gas and his bumper is spittin black meaning rich get it fixed i bet his shit is drinking alot of gas for a 4 more like a 6

eh, its not THAT bad, it definately makes ur car sluggish, moreso hinders your engines acceleration. baasically u run rich, and waste a lot of gas! lol i had no O2 sensor for 2 months, just cuz i was over at college and broke as fudge! LMAO! but id still drive 300 miles and only use 3/4 of a tank with no O2. now i can go 280 miles on ONLY half a tank!!!

wow! 300 miles on 3/4th of a tank? I didn't think carbon fiber hoods help that much.
