If i drive my Fiat Punto 1242cc Mk1 with its Lambda sensor disconnected from the cable will it do any harm? - the engine idles perfectly when it disconnected and lumpy idling when it is connected.

I don't fancy changing the sensor at the moment I will get around to it later but if I leave it disconnected for the time being will it cause any harm or use any more fuel etc...?
