HOWEVER, it is super rare for two sensors to fail at the same time. More likely you have an air-fuel issue, causing issues w the sensor readings. The DME reads this as "o2 sensor issue"

Do you have any codes??

Or did you take it to some shop, they said bad sensors and you want to do it yourself.

If the car has over 60k, prolly should replace them as they are maintenance items, but may not fix the issue.
