The car is a 1992 Buick Century 4-cylinder Iron Duke and it does not have an OBD2 scanner plug-in but it has an OBD1 plug-in so I don't think O'Reilly's or AutoZone would be able to check it seeing it's an older car and also like I said the light comes on but then goes off a few minutes later so there's no telling when it will stay on and how long it will stay on before I can get to a mechanic to check it that is the problem too
