scrap yard - all cars from 92 onwards have them
what do you want it for?
(ie to replace an existing one or to use it to map the engine?)

If you want to use the lambda sensor to help map the MS then a wideband unit is far superior, it actually tells you the air/fuel ratio rather than
just too weak or too rich. You will need deepish pockets to buy one though.

You can use a narrowband on the autotune - but get Paul to set it up with his wideband lambda and controller.
Narrowband is perfect for tuning upto half throttle - but you need the wideband after that 
Probably better to chat to Paul than spend the £150 for a wideband. They don't advise running with a wideband full time as they are easy to
break apparently.

If you believe you're not crazy, whilst everybody is telling you, you are - then they are definitely wrong!

Hmm strange then - that the wideband kits you buy contain 'NO' warranty - as they are easy to FECK up???
Unless it's just the controller that breaks down and not the actual probe?
Dunno - all I know is it wasn't recommended and at £150 a pop - wouldn't like to keep chancing it

Easy to break??
Fitted to Hondas in the mid 90's, one either side of the cat. Seemed to last ok there.
Now on most of the upper end motors. And VW's as previously put.
Can't use them full-time?? Time for a reality check and some common sense. 
Cheers,
Syd.

Any mid mid 90s Hondas I have had contact with were normal "thimble" Zirconnia narrowband 3 or 4 wire types.
The wideband ones are 5 wire planar types
Used Lambda sensors are a pain to remove often then weld thrmselves into the down pipe and only the application of spot heat to boss will alow removal
- usual either oxy-acetelene or a dab with the MIG torch.
Lambda sensor also slow down a lot with age best to buy new
either http://www.gendan.co.uk or http://www.lambdasensor.com/ are good sources of info and cheap sensor.
For universalnarrowband sensor http://buypartsbuy.co.uk is very handy and low cost.
The Bosch Wide-Band Lambda Sensor (LSU4) is part number 0258006066 or the NGK equivalent
For widebandb AFR info ty http://techedge.com.au/vehicle/wbo2/

Wideband Lambda sensors were fitted to Hondas since mid 90's in California, and a couple of other USA states.
Europe wasn't so fussy about emissions back then.
Point is, they last as long as any other sensor. Need to be preheated though, and definitely don't like lead or lead substitutes.

The sensors themselves aren't actually that expensive; most of the £150 or so is in the electronic gubbins to drive it. This is pretty reliable.
