if so did ur car run like chet?

3.point.2

i dont have an O2 sensor and my car runs fine

egcivic

is ur car obd1 or 2
cuase the obd2 cars have more than one and i think can run fine without one of them
but my car the o2 went out, i got a code and my car ran like crap

forcefedferio

yeah for like a day because when i put my header on the o2 sensor was pretty much welded into the stock manifold...long story short car idled like complete *** and ran like ****

engines obd2, but the car and ecu are obd1. i dont have any O2 sensors in. my ecu throws an O2 sensor code, but my car runs great and i get 30+mpg on the highway

30 mpg on the highway is pretty bad, but anyway, you can run without it, I don't see why though.

pretty bad? read my name, i dont have a d series

slowturbocx

i dont run a o2 sensor d16z6 turbo, runs good 25 mpg too

SVOboy

Wow, a 2.3 liter getting 30mpg highway, I'm mystified. I've never seen anything like it.

Just get a program on your ecu that supplies a constant o2 reading... like hondata or uberdata or something, then you wont need o2 sensors or any of that crap.

Edit: btw i get 22 mpg, so dont listen to my advice

i run w/out one almost all day, but i had it disabled, so i got no cel, not the best idea in the world unless you trust your tune very much.

i havet ran with an O2 sensor for more than a year and i get 35+ mpg

egcivic

im not saying without a doubt ur car will run like crap without an o2
but mine was almost not driveable without my o2 sensor
im sure not all cars get 30+ mpg on the highway without an o2 sensor *shrugs*
you gave what your car did and i gave what mine did no need to get hostile

my car gets excellent gas &lt;PG and I have been running with basially no O2 for 1 1/2 years. I swapped to 4wire for turbo, but that didnt last long, so I went back to my regular HX ECU, but with a 4wire sensor. SO basically it isnt even reading the o2 sensor right now and drive slovely

Soccerking3000

well i run open loop all the time and i tuned the vacuum columns for fuel economy and use the IAT compensation along with a few other modifications.

schardbody

well, the o2 only compensates 5% anyways, its not that useful, i mean 5% of 30mpg isnt much.

vtec25

well mine is running like crap like its only on 3 cylinders and i get bad mpg dont know exactly cuz my speed sensor is bad therefore no speedo. plus my tps is broken off.

schardbody

and your worried about the O2. you need to get the TPS fixed. your ecu is basing fuel trim solely off the map sensor right now, and its probably pig rich, which will kill the o2 eventually if not already.

That is damn good, I am jealous...I don't get 30.
