My Son's car has a O2 sensor error (according to Advanced Auto) and we
don't have a shop manual, looked online for a IPB or other and can't
seem to find clear information.

Anyone know the specific location of the two sensors and able to give a
good enough description that a blind man could find them?

Thanks

One is in the (top of, I think) exhaust manifold and the other is just
behind the flex pipe in front of the rear converter.

We opened the hood and I was amazed, so dang easy it wasn't funny. All I
had to do was remove the heat shield (4 bolts) and I was able to use a
22mm wrench to losen and remove the sensor - the bad thing is that none
of the auto-parts places have the 5 wire version, dealer had 2 and they
cost $130 for the top sensor (before the Cat Conv) - installed it, went
to Advanced Auto to reset the code, and it's worked fine since, even
getting better MPG...

As a side note, the dealer would not reset the code unless we paid $98
for the service, but Advanced Auto will check/reset codes for free.
