what exactly results from a bad 02 sensor? i have herd it makes your car run like ****, bad gas mileage and what not... anyone care to further inform me?

 

bad o2 sensor = run very very rich. u'll get bad gas mileage and u'll prob get soot all over the backside of your car.

 

what about performance wise?

 

in my experience the car was not too much slower but it was noticable.

 

hmmm o.O alright lets see what happens when i put in the new 02 sensor on like wed or thurs when i get it

 

i think my car is getting more mpg thats about it...

 

im running w/o an o2 sensor right now, according to trip meter, i got 60miles so far, and half my tank is gone. (needle is a tiny bit below half) so... u do the math. im prob getting 8-10 mpg.

BB6 w/ heart of a hummer is what it is right now
