1.no you dont have to get it fixed
2.each sensor is around $75
3. measures exhaust for optimal air/fuel mixture
4. ****tty gas mileage, failed emissions test, clogged cat

thank you for your help!!!!!
:nods:

my ngk sensors were over $200 a piece

Is that used? Cause I would love to know where you get your sensors from if that is new.

call A&A discount parts. Thats about what i pay for them from there. Only thing is the place is in hamilton, which is ok for me.

I wish I would have known that back in the summer! Oh well.

Mine were NTK which is an offbranch of NGK. I got mine at walmart parts counter in square one, i get 10% off because im an employee

So what are they at retail? Didn't know Walmart sold O2 sensors.

is urs o2 sensor or the secondary o2 sensor. cuz I had to replace my secondary o2 sensor recently, and it cost me $230...the o2 sensors are the most expensive sensors to replace. it doesn't affect the engine or anything, it juss give u bad fuel economy.

dunno bout retail. Its not walmart that sells it, theres a seperate company that runs inside walmart that deals with parts.

I bought a used O2 sensor from Lucky Star and than i passed easily on my emmisions. I was told never buy aftermarket O2 sensors cause they just dont last as long as OEM parts. A used one costs $60
