So I have had my 87 cutlass supreme for about a month and I noticed that once the car warms up and I come to a stop the choke/oil light comes on, its not just when I stop sometimes it when I let of the gas like when im going down a hill. Now if I put it in nutrual when going down a hill or when im stopped the light doesnt come on so what is the issue I have a rebuilt olds 307 I took out of a 85 salon that caught fire,so if it means the engines shot its no big deal just want to know whats going on
