I have a 94 and i believe i have the same stock 02 sensor .
Should I change it? What would be the benefits of changing it? Need help because i don't wanna change it if i dont have to, it's kinda expensive.

 

your car will benefit nothing.
if it aint broke...

 

Are you throwing CEL (Check Engine Light)? If you don't get any CEL, then don't worry about change it. However, if you're throwing a CEL due to an O2 sensor, then you should change it as soon as your pocket will allow it.

The O2 sensor basically let your engine achieve stoichiometric (sp?) air:fuel ratio by "sniffing" the exhaust gas. If it is broken, you could run lean or rich, depending on the problem with the clogged/faulty O2 sensor. (And, many times you won't pass emissions.)

To put it simply, your engine won't run at an optimal A:F condition which is .

Hope that helps.

 

thanks for the replies
Whats the probability of my o2 sensor not working to its full potential?
it's the original one from 94.
Because I cut the o2 wires a year ago (i was changin my header) and the check engine light didn't even go on. I rewired them back and it was fine. I was just curious because my mpg is not as good as it should be. Less than 300 but close per full tank of gas.

 

i have a 94 GSR also and my O2 sensor went bad and i had to change it. If your not getting the CEL light, then dont bother to mess with it until it does.

 

.....ok.....i'll probably leave it alone
