What kind of Chevy? Year? Miles?

Can you get any codes pulled at your local auto parts store and post them here?

If the idiot lights are randomly going off and on instead of regularly flashing, then maybe you have a bad ground somewhere. Older cars are notorious for corrosion on the wiring. First place to check would be all the battery connections.
