RE: [DML] LAMBDA/OXYGEN SENSOR PROBE

["John Hervey" <john@xxxxxxxxxxxxxxxx>]

Mike, 
Normally if the car isn't hunting the 02 is bad. When it's hunting is a
signal the 02 is working. Doesn't mean it isn't working the best, but it is
working or it wouldn't hunt.
As far as the broken threads in the pipe, It's time for the cutting tool.

Subject: [DML] LAMBDA/OXYGEN SENSOR PROBE

While working under the engine of Josh's car, I noticed the ceramic was
chipped on the sensor so I decided to go ahead and replace it, since it was
one of those things that could have been affecting the 'hunting' idle.

I put the wrench on it, twisted CCW, and much to my surprise it popped loose
easily.  PO must have used never-seize, but that's asking a bit much, since
he never did anything correctly maintenace wise.  After I get it out, I
realize that he did not install a crush washer and the threaded part is
still in the exhaust pipe.  I had the sensor in my hand and only the
outermost threaded part is left in the pipe.  Has anyone had this happen and
how did you get it out?  I tried an easy out, but it just won't budge.  I
used PB Blaster, Corrosion X, heat, and a few choice cuss words, nothing is
working.
