When did most of you change the O2 sensors
#5
O2 sensors i have heard are suposed to be replaced every 100K miles or so. That is the average life span. I have yet to change mine, but i from what i have been told, they can stop working like "new" and loose efficiency over time, even before they throw a CEL. If you feel like you should change em, change em....dont wait for the CEL, not like it matters, but 02 sensors effect alota things that we value in our maximas like fuel mileage and power, etc....
just my .02

I did
When I got my car I thought maximas had the worst gas mileage ever till my first meeting with the SES light. Went from 13 mpg to 22 mpg. The first one went at 123k and the second front one went at 140k. Replaced both with walker oem's (they come with new ties and anti-sieze). They're easy to replace even with my rusted out exhaust system.
