partly true...Originally Posted by orion
unless your O2 sensors are known to be bad, new ones will do nothing to help. save that money for gas
O2s wont always throw codes, unless very bad...
but if they are borderline, they can start effecting mileage
and show no code.
Generally we change them on our cars and customers cars every
85-100k. Mine look to be the oe units and have 105k on them.
I dont mind changing them in the near future, just to be on the
safe side.
Thanks.
