it came on saterday when i was racing around in the sand...i got the code today (Po171) the guy at autozone told me it was a o2 sinsor...but i want some more input, but also i had drove 3 hours that morning,then it sat all day then i drove it at night,and after a bunch of bumps it came on... THANKS

 

That's an engine lean code...not an O2 code.... this is why the auto part store guys aren't paid to think........

anyways ... you probably have a vacuum leak somewhere in your pcv system... go back to the auto part store, and get a new PCV and grommet that mounts it into place... the grommet is probably dry rotted and leaking... Those will cost you $7 for the both of them... if that doesn't do it then follow the pcv line up to the TB and check the elbows of the line for leaks...

do a search for the code... it's covered about once a month

good luck

 

ok thanks...is this something i need too get done as soon as possible, or can it wait a littel bit....thanks

 

as long as it's not driving terribly it'd PROBABLY ok to wait...however.. that is saying it is a simple vacuum leak... and not something else

 

Don't wait too long. That "lean" code description is misleading. The computer has actually maxed out the fuel so it's running rich. Your cats will get toasted in short order if the problem doesn't get fixed soon.

It ain't an O2 sensor.
