As best as I know, 72 is the Speed Sensor - Is the speedometer not working? And 41 is the Opti - engine running poorly? If you want something quick, you can subscribe to Alldata - www.alldata.com - and at least get the Trouble Tree Charts. Otherwise, Helms is invaluable.

For a 91 OBD-1 Vette the codes should mean:
41 - Cylinder Select Error Circuit (1985-1991)
72 - Gear Selector Switch Fault (Start Lockout)
41 -> Check wiring at ECM. Possible PROM failure, or incorrectly seated PROM. Reseat PROM. Possible ECM failure.
The site recommended by Mike C4 is a good one, but the page he recommends is not for your 91 Vette. You need the ECM chart for 91 5.7L VIN engine digit = 8. Try http://www.troublecodes.net/GM/90-91_578.shtml
Some of the code meanings changed between vehicle years. If you use the definitions from later years than your 91, you willbe chasing your tail needlessly.

And there is real difference depending on where you get the code from. In Eric's case, he is getting the code from the CCM, not the ECM, so the code number is different.
