I had this problem on my own 87 lxi. What I found was the water temp sensor was bad, that took are of the light. The surge problem you talk about, if it is surging while driving, fuel related, check the fast idle valve located on the side of the throttle body. There are two srews on the top of it, there is a plug that can come unscrewed, tighten it back up it may take care of it.
