With a the manufacturers computer (which they only provide to their dealers).

I will assume that the car is fuel injected/computer controlled carburetor. You will have to replace the intake, the carburetor and the distributor. These parts can be found at your local junk yard. Care should be taken when selecting these parts, that they are taken from a non-computer controlled chevy. If not available, these parts can be purchased from a performance parts dealer, i.e. eldelbrock, MSD.
This car is not built with one, that function is done by the computer controlled fuel injection system.
on a computer controlled vehicle you have to reprogram the computer and on an older vehicle with a carburetor you have to change the jets in the carb.
Incorrect idle mixture (carburetor), or sticking IAC (idle air control), computer controlled engines.
As far as I know there is no carburetor in an 89 Chevy corsica.
no one knows

No, it's computer controlled.
Depending on how this mower got out of tune is how you are going to know how to tune it back. It may be as simple as adjusting the mixture screw on your carburetor, or as difficult as filing the points (older engine) or replacing the diaphragms on the carburetor.
