I'm looking at a 1993 Corvette 6 speed. It's a two owner car, the second owner being an old friend of mine. He passed away in January of 2015, and his sister has decided to sell it. It's black on black with a leather interior, and only 17,000 miles. I can get it pretty cheap, but wondered if there were any well know trouble spots with that year. Not planning to autocross it, just a street ride.

Dove deeper into the car. A buddy brought his Snap On diagnostic stuff with him. The ECM would not communicate with his equipment. The fuse was good, he was surprised it wouldn't read. We drove the car and it ran as bad as last time. We managed to get a couple of codes by crossing the obd pins. One was H41, the other was H72. Crossing 2 different pins made the check engine light blink one long and 2 short times. According to what we had this indicates "12" which is good. The gas smells horribly stale, and unplugging some of the injectors made no difference in the way it ran at all. The anti-freeze I saw on the cross member seems to be dripping from the t-stat housing. I'm wondering now if the problem is the stale fuel causing the issues. I don't think I'll be buying the car, but could the fuel be the main culprit?

Fuel is the main requirement for fire and bad fuel will make an engine do all kinds of stupid things.

A few years back I bought a low mile SOM Camaro SS. I started it and it ran ok, but I didn't drive it. When I picked it up I found that it didn't actually run under any real load at all. It popped and kicked and banged and generally ran poorly (if at all). I babied it home to Ohio from PA trying to burn all the fuel I could. I stopped and filled it up with fresh gas and it was better, but still not really drivable. Ultimately it took fresh gas and new plugs and wires to get it to run properly.
