Easy answer? bad spark plug. Check it.
Next check? the wire. Substitude a good wire and start the engine. If it runs good, that's what it is.
Next check? Coil pack. Or the gas injector.
Next? Get Chilton's automotive repair book and go to the section that shows your Chevy. Then go to the troubleshooting section.
