Testing a Lambda Sensor

[redjohnuk]

Hi all

Does anyone know how to test a Lambda sensor to see if its working correctly. I run a 1.6 Mega Grad on a Supersport EU3 ECU and its been giving me a few running issues as in revs sticking ranging between 800 and 1200 {up and down}. 

Changed the TPS, the ICV and both water rail temperature senders......and done various resets.

Anyone got any ideas?

Thanks

Previous discussion.

But I'd guess that most people try another one and see if it makes any difference.

Done that...seems that the readings im getting are within the normal expacted of .2V to .9v and very quick changes. Also makes a difference the running when disconnected after the engine started....so its not that ( i think ) 

I have discovered that with the ICV sealed off the engine starts but needs throttle to keep it going until warmed then it runs fairly smoothly. Unsealing the ICV the revs pick up and stay up....Changed the ICV but no different.    Confused....you bet
