Default 89' SSE, SES light reads code 64

I have not been able to run down what code 64 is supposed to tell me. I even called a Pontiac dealer, they did not know either. Can anybody help me with this one?
I pulled it myself with a jumper wire to terminals A-B under the dash if that makes a difference....Thanks

63,64,65 - Exhaust Gas Recirculation Flow Check

IOW, you have an issue with your EGR valve. You can remove it via 2x 10mm bolts and try cleaning it out with some carb cleaner. If you have to buy a new one, Ebay is the cheapest I've found. I got one for about $90 shipped for an AC Delco branded part.
