hello people
my check engine light come on,so i stopped @ autozone ...
they told me my o2 sensor is bad,and i have a slow flow or response????that was no.2 problem. the sensor is $238 .
my question is.....how do i find out witch sensor is bed???
we got 3 on our cars..and i find some online for $75 - 100.
sorry about spelling ,i am still american -hungarian.thanks

 

i think someone on here said that autozone has this device that plugs into your car (located beneath your coin tray) and it tells you which o2 sensor is bad. they do it for free or something. you might need a new fuel injector too or something. make sure your gas cap is on tight too....it takes like 3 clicks to completely seal the gas cap
