Lamdba Question

Lamdba Question
I have a uk my00 turbo 2000 which has hesitation on light throttle. Sort of like, its pulling on and off gently. I tried disconnecting the lambda plug and the car drove the best its driven since I've had it! Anyway I bought a spare lambda off a fellow member on here a while ago, however after fitting it, its instantly gone back to how it was before (if not a fraction better). I tried an ecu reset and its made no difference. My question is, when the lambda is disconnected does it cancel the maf and lambda signal so that it runs a base map for both or does it just run the base map for the lambda? Or do you think that this used sensor ive bought is duff aswell? If so wheres the best place to get one from thats a good price and direct fit?
Thanks

should fluctuate between 0v - 0.9v depending on how you are driving, if you floor it, it should go up to .9v and on overrun (foot off engine braking) it should read 0v
if seems slow to react to driving conditions it may be on it's way out. They tend to make your car run rich if they a fubared

Mine went yesterday too!
I'm running very rich, by the look on the AFR it's stuck around 0.7~0.8v.

Two of the three wires are the heater + and -, the other is the signal. If you look in the connector plug one of the terminals should be a gold colour, that's the signal. Put one probe to that wire and the other probe to earth and read.
Day to day just a narrow-band AFR gauge Matt.
Not as accurate as a wide-band but told me instantly that my Lambda had gone.
