If you have a non-turbo, you've got the LH2.4.2 system. You can read out the fault codes yourself. Check the FAQ, 9000 section, under LH Fuel Injection System overview. Near the bottom you'll see "To pull the fault codes from the ECU memory" To clear the faults, you need to read out all the codes first. Disconnecting the battery won't clear the faults.

If you have a turbo engine, you have the Trionic fuel injection system. To read out those codes, check out the Townsend website, specifically

http://townsendimports.com/Web/engine_folder/Trinonicflashcode.pdf

To clear the faults on a Trionic, you need to disconnect the connector for at least five minutes. I suspect you can do the same by disconnecting the battery for at least 5 minutes.

If you clear the faults and the CEL comes back, it means something is still amiss. The CEL is the engine control's only way of communicating to the driver. All faults get lumped together and drive the light - both really serious ones, and really minor ones.

In general, if the engine seems to be running well, you're probably OK. But it would be nice to know what the original problem was. As an example, you may have had a bad misfire on one cylinder. That would explain the rough running and the CEL. That misfire could have been dumping raw gas into the catalytic converter, which will quickly ruin it. The misfire cleans up, and the engine runs just fine. But the Cat is now dead. I can't remember if the Trionic in '93 had two O2 sensors, but if it does, it'll now give a fault from the second O2 sensor. And if not, a dead Cat means no passing the emissions test next time.

This isn't meant to scare you - that's just one of literallly dozens of possible faults, serious and minor. In general, if the engine is running fine, you're not damaging anything. But it would be good to know what's up.
