1993 LT1 Corvette throwing a H41 code in 4. I can't seem to find what this code is telling me.

An H code is historical, meaning it happened some time in the past. If it were current it would be a C code. I suspect a corroded pin in one of the connectors associated with the ignition control module.

Thank you. I replaced the ICM and that removed the trouble and fixed the problem. I purchased 2 aftermarket ICM's on eBay and they triggered the code and resulted in a no-start condition. I purchased another one, different brand from AUTOZONE with a lifetime warranty and that is the one that got the car started and removed the trouble code. It was interesting in that the 2 aftermarket ICM's both passed the test but would not start the car. In any case, thanks for the reply.
