few causes, often coolant temp sesnor is to blame, does it have lambda? get it plugged into a diog machine, like a snapon one, then look at what all the sensors are reading out, can find the problem that way usually.

Ollie check the air pipes, a small split in them will cause a real shitty idle, look round any clips/joints for deteration of the rubber.

Leaaking injector? had this on the corsa, tested them and one was chucking in twice as much as the rest due to it not holding pressure.
