When to replace O2 sensor?
I get conflicting information on this. Some say 100,000 miles, others say change at 60,000. I have also heard the term "lazy sensor" which I think indicates a slow response to fuel /air adjustment needs.
I have no known problems. However, I am into preventative maintainance and I have almost 60,000 on this sensor.
BTW, I have heard from my indy to always use an OE Bosch O2 sensor. For some reason they seem to have a lower failure rate than OEM/aftermarket bosch sensor. Not proven.
TIA
