You'll need to find someone with a code scanner. I believe that after the codes are read, it resets the computer. I've heard that places like Autozone will scan your vehicle for free, figuring that you will then pickup the parts from them. All alse fails, a small piece of black tape can cover that pesky light for a really long time, like in my '78 El Camino, some diode failed somewhere which caused the generator light to come on, but the charging system still operated normally, soooo...... a 1" piece of tape "fixed" it for the next 10-12 years or so, it was no doubt still lit when I sold it.

You certainly need to get it checked out. I've been an auto repair tech for
over 20 years, and hate to see people spend more $ later for putting things off. The check engine light is probably illuminated due to a sensor or sensor circuit (wiring) failure. You could have the code read and then erased at AutoZone or another place like that. But.... there is a high probability that the light would come back on in the next 5 minutes to 2-3 days. Most likely you've got a bad O2 sensor (there are 3-4 on that truck), a faulty fuel injector (GM had problems with those years), or an evap system leak (possible loose gas cap). If the problem is relatively serious (fuel control related) and you ignore it, you could damage the catalytic converter internally which will cost big $ and won't be covered under warranty if you neglected the check engine light for a period of time. If your check engine light ever flashes consistently, get the vehicle to a shop **NOW** or park it. A flashing check engine light means that there is a major fuel control system failure and catalytic converter damage can result very quickly.
