[s-cars] Bank1-Sensor1 Internal Resistance too High

[Keith Franchetti]

WTF?  The rest of my message got cut off.  So here was my actual question,
and the rest:  From what I've been able to tell, this is an O2 sensor?  But
does anyone know where that one would be located, as I guess the car has 3,
and I don't have a decent manual for this thing yet.
By the way, someone here on the list helped me locate the relay for the
servotronic in this car when I first got it, and I don't think I ever said
thanks (because my email was blocked from the list at that time for some
reason).  Anyway, I love it without the servotronic, so THANKS to whoever
that was back in September.
Would love to change out this O2 sensor ASAP, like before the trek from VT
to MA for Thanksgiving, as my fuel economy has dropped from 24 to 18.
(Lucky price of gas has dropped  too).
Thanks for the help!
