I have exactly the same problem as you , car cuts out when you start it ,have to keep it revved till it warms a little to just idle, stuttering / uneven performance.

Changed Throttle body - still the same
Changed the EGR - still the same
I had it checked on the error codes P0505 - Throttle body actuator , Voltage high
Mass airflow air intake temp sensor

I had it all checked over by an Ex-Vauxhall Tech who went through all the checklists for the fault codes and nothing was wrong.
His conclusion " The ECU is the problem "
There was nothing else it could be, apparently this is a common error code for faulting ECU's on the facelift vectra, try googling the code and take a read.

I am currently looking for a 2nd Hand ECU complete with Immobiliser and key/chip , if anyone on here knows where I can get one please call me or send a Private message on the forums please !!
