If you're talking about the newer, cheaper WBO2s (I don't believe they have as big a range as a traditional WBO2s) you're usually talking about 2006 and up honda stuff, though I have heard that there were some used by toyota early 2000s, maybe 99, but have never had my hands on one for sure.

A lot of stuff that I've heard a lot of people call a 4 wire WBO2 is really a 4 wire NBO2 (NBO2 with a separate heater circuit)

About to get cold feet.

I would love wideband but guess I should buy pizza instead.

Was getting 18 mpg but determined carb was to lean.
Rejetted w/ basic plug readings and now getting 16mpg.
Car running perfect...based on seat meter.

Still interested in Junkyard special wideband. I don't mind collecting data on multimeter. Not like I will need to get readings every day.

02 sensors generate voltage when exposed to oxygen, from approx 0-1 volt, with stoich being around 0.45 volts. Closer to 1 volt, lean, lower than .45 volts, rich. A 1 wire sensor has to be heated to 660*F to read, before that it is inaccurate. If you go with a 1 wire, mount it as close to the manifold/header as possible, or it will cool too much at idle and fail to read. This was a problem back in the early days of electronic fuel injection, as the vehicles would fall back into open loop when idling for extended periods. That, coupled with environmental law changes, lead to the adoption of heated sensors to speed entry into closed loop operation. It can be thought of as choke on or off.

Production cars have no need for a wideband O2 sensor, You will not find one, Car makers know the fairly narrow range their engines are gonna need to adjust for, That is why they overpay all those engineers the big bucks .

I'm with 001mustang I don't mind reading a multi meter if some one could jump in here and tell me how to do it. I don't even mine using a two or three wire 02 sensor.

I might just grab a few O2 sensors next time i visit local scrap heap.
weld bung in exhaust near headers.
google for voltage vs O2 specs.
if no specs:
voltage reading w/ car off (post hot lean idle)= 14.7 O2 (maybe)
volt w/ idle tuned lean= lean O2
volt w/ idle tuned rich= rich O2

test drive car and see what i get.

if lazy could just buy an elcheapo narrow band; save lotta time.
if your nice...maybe santa will put a wideband under tree.

No, it's there, 5-Wire sensor. Just one of the knurled Gauge mounting nuts was missing. You can see all the parts in the Pdf. instruction link.
I just looked it up on Summit > http://www.summitracing.com/parts/ATM-4378/ I didn't know it was that much $$.
