Should I change my o2 sensor
My truck is a 93 T-100 4x4 pick-up totally stock with 131 k miles. It runs great and I do NOT have a check engine light. The manual says to change the O2 sensor at 80K miles but I never did because I never had a problem. Should I change it or leave well enough alone? Bob

I'd leave it alone if you have no issues. ie. gas mileage dropping/check engine light. They're expensive to replace.
You can test yours with an electrical meter to see if it's ok.

Back in the day the O2 sensors where recommended to be replaced at a certain service interval or mileage. The new way of doing it is to replace them as needed with no set service interval.
