christ could be a number of many things:
Idol control valve
Throttal Positional Sensor
Inlet manifold
Inlet manifold gasket
Map reader
Air mass meter
ECU
1 of the wiring looms
lose connection from 1 of the wires connecting the sensors to the ecu
find the problem by doing the paper clip test on the ecu
failing that send it down to a proper vauxhall main agent and leave it with them, they shouldent charge for trying to find the fault, just the part and labour to fit when they do

u missed off egr valve that can cause the light to come on without any major symptons and is quite common as is the idle air control valve.
read this thread on how to read ecu's and fault code's
