I'm getting ready to do some spring maintenance on my IROC and wanted to know if others on the board change their Oxygen Sensor on a regular basis, as a part of preventative maintenance.

Can the sensor be serviced (cleaned)?

 

i do it every other time i change the plugs.

 

I change my plugs annually, and I didn't do my O2 sensor then. The car does not idle quite as smoothly as it normally does, and my No. 1 cylinder burns some oil, so maybe the sensor has alot of carbon buildup. It's been about 2+ years, 20k miles since I replaced it. Guess it's time.

 

O2's cant succesfully be cleaned with any reliablilty. The recomended replacement is around 50k but i just wait till they go bad.

 

O2 sensors will get "lazy" with usage. Must change every 50 to 100K. Wide range but depends on overall condition of engine.
