how do you test you're O2 sensors? is there a way to know if its time for them to be changed, other than a CEL ?

Generally if one's milage drops off, that is an indication. Some solvents and such will shorten their life as well.
60K miles is a decent rule of thumb for replacement. Too bad they cost so much.
Good luck.
Sweet, Insane is gonna buy me new O2's.Insane3D said:Cost too much? Brand new Bosch units are only $39...$80 every 60K-80K doesn't seem like much to me for the money saved on gas mileage...

Frame of reference: Our HEGO's are expensive compared to some EGO's (though HEGO's last longer).
