What does a faulty Lambda Sensor feel like?

[debaron]

I have a 4.0 Serp Chim. Often feels a little rough around 2000 rpm and higher. Worse when the engine has warmed up. Power feels down too. Had it dyno'ed by Pete at Roath TVR and it came back fine with regard injectors and HT system etc. Could a intermittent/faulty Lambda cause this and does anyone have a set of instructions for testing the OP of the Lamda with a DVM?

PS - They're the two probes that stick out of the exhaust pipes just after the clips right?

They switch between about 0-.8 volts about once a second at tickover when hot.
