Hi,
I have recently replaced both of my oxygen sensors, but my check engine light still comes back on in a couple of days. I can't get the car to pass Marta. 1996 Volvo 850 GLT. That is the only thing with the car that is a problem. I am driving on expired tags as I continue to try to find out why I am having this trouble. Does anyone have any ideas? Please share them.
Thanks

Did you get the updated harnesses with the new sensors?
Do you have any air leaks?
Do you have any exhaust leaks?
