Secondary lambda sensor?

If it is i think the procedure is to take it out and tape it out of the way, then blank off the hole it was screwed into. that should clear up any problems as it will be 'smelling' fresh air from under the car instead of un-cat'ed fumes inside the exhaust.

Sounds to me like sumat to do with throttle assembly and intake manifold/throttle body. Although my knowledge doesn't extend this far at the moment.
