I have a 90 Storm and the problem may be with the fuel injectors (yes it is fuel injected!). It also could be with the Idle Air Control IAC sensor - that it right up there by the air intake.
These are nice cars with nice mileage. Maybe older, but I am not paying a monthly payment to a bank for a car that is sucking down gas. If you can fix it, that is the smart thing to do. Most of the problems you will see are easy enough to fix since you can already change the plugs. Just check the Storm forums for a lot of good information.
