throttle body is not letting enough air in.
Idle speed servo, stuck or failed.
The idling speed cannot be adjusted for fuel injected models. It is done by the ECU depending on inputs from various sensors. If the idling is erratic it is best if the car is taken to the vauxhall dealership who have testing equipment called TECH 2 which diagnoses the problem.

You do not provide enough information for a good answer. It depends if it is Fuel Injected or not and other information. Possibly vacuum leak or idle speed too low.
The first thing to check if a fuel injected car is idling high is look for (listen for) a vacumn leak. look for a broken vacumn hose. 2nd, check the idle air control (the IAC) - However, if it is a carburetted car then you need to set the idle lower.
No spark?
American car! I would say the 1957 fuel injected corvette
check the car ; and if it is fuel injected send it to the shop because the oils can damage your hand if touched.
exhaust leak or a possible fuel line leak
my experiencess with vehicles that cut out while idleing would be a fuel filter or fuel pump problem.
It is inside the fuel tank on fuel injected models.
If car is fuel injected (which I assume it is) it does not have a choke
that depends on size of engine
If this car is fuel injected, it is located behind the passenger kick panel. If it is not fuel injected, it does not have one.
