This is mostly for Sid Woods information as he is keeping a running tab for
mixture information. I have an O2 sensor on both exhaust with a switch to check
back and forth. Both of the O2 sensors were replaced in June of 2011 and both
quit working some where around SNF of this spring. Both with inn a week or so
of each other at around 105 to 110 hours total time. While doing the annual
this month I replaced one and too the bad one and soaked the sensor end in
lacquer thinner for a few minutes and cleaned it up with a wire brush and put
it in the other side just to try it. To my surprise it worked. It might be
showing just a shade rich of what a new one indicates but still very close and
really I only flew for about 20 minutes so not much checking done. I will keep
a running tab on the difference between the new and the old and see if it works
for a significant amount of time. I just gave it a try for curiosity and had
nothing to loose. Now I have to do a little research to see how these rascals
are made inside. The thing that gave me the idea of trying to clean it was it
just looked like the lead build up was closing the tinny slots on the outside
of the sensor.Joe Horton,Coopersburg, Pa735 hours
