Cleaning O2 Sensors
This procedure will clean the O2 at the same time you test it. Basically you are burning all the crud off of there.

If you look at the tip of the O2 you see very small slits because O2 functions are inside
that tip. A spray cleaner really would not get into those slits very well much less the junk coming out of them.
As O2 ages it gets slower/lazy so if they have more then 30-40K miles they really should be replaced for they might still work but not as well as fairly new ones.
