First piece of advice, and this is really good advice..

DONT take your corvette to Meineke!

Sorry to say this but i woudnt take thier word on your PCM at all, get it checked out by somebody that has experience with GM PCM's IE a GM tuning shop in your area or a Dealership.

I would doubt the pcm would be bad by it throwing a missfire code for cyl 3. did they check the plugs, wires, Injector plug, ect? It is something simple probably.
