Corsa engine revving in neutral

When my Vauxhall Corsa 1.2 petrol is in neutral the rev counter is at around 2000rpm and the engine management light comes on. However, the revs go back to normal once I am driving, but go high again once the car has stopped. Any idea what's going on?

Faulty idle control valve or throttle position sensor.
