It probably hasn't set a fault, the systems in 1994 did not have the level of sophistication to report the individual issues that get reported to memory, since they didn't have to. What have you done so far? Did you try to fix it yet or are you just searching for something?

An ignition misfire can be seen on a scope, do you have any diagnostic tools?
