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!
