What you likely want to do is one of the following:
* Reset the PCM: This clears various learned parameters and can help with some drivability issues. The most common method is to disconnect the negative (-) terminal of the battery for about 15-30 minutes. This allows the computer to completely power down and lose its stored memory. Reconnect the battery and let the car run for a while for the PCM to relearn its settings. Caution: This will also reset the radio presets and clock.
* Reset a specific system: If you're having problems with a particular system (like the air conditioning or radio), there may be a specific reset procedure for that system. Consult your owner's manual for details.
* Deal with a fault code: If a "check engine" light or other warning light is on, the PCM has stored a diagnostic trouble code (DTC). You'll need to either use a scan tool to read the code (a mechanic or auto parts store can often do this) or have a mechanic diagnose the problem. Simply disconnecting the battery won't solve an underlying mechanical or electrical issue.
In short, disconnecting the battery negative terminal for a period of time is the closest equivalent to a "reset" for a 1992 Corvette's computer system. However, if you're experiencing a specific problem, identifying the root cause is more important than a general reset.
