Tracy
you amaze me!
When I pulled the O2 sensor, that is what had happened! I cleaned
it off and also the EGT probes and when I fired it up, the O2 sensor started
working!
Now I am wondering about the threads of the various O2 sensors. I
cut the O2 sensor boss off of the Renesis manifold and welded it on my
exhaust. I am using the Bosch O2 sensor that you suggest in your EC-2 install
manual. I noticed that the threads were boogered (technical term!)
up. Does the Mazda use a different thread? I have an old ’88 engine
that I took the O2 sensor out of and it was boogered up as well. It was a
Bosch also but a different part number…12 something instead of 11
something.
Any thoughts?
Thanks for the assistance, guys!

What Bob said for me too. I always use anti sieze (on threads
only) and had no problem. Of course there is the possibility that you had
a gob of it fly off the EGT mount and land smack dab on the O2 sensor.
That might do it harm.

Hi Bill,
I'm pretty sure I used the copper anti-seize compound on my O2 sensor.
I lost two of them in the first two hours of flight because the wire
broke off. It was unsupported for several inches and I think it was
vibrating. I don't think the anti-seize will hurt anything as long as
you don't get it on the sensor itself.
