I have a 1982 Cavalier CL with 1.8L engine that has been in the family since 1983. Driven 72K miles since new. We now have a check engine light on, which our local repair shop is having difficulty diagnosing. Evidently, this must be one of the first vehicles having an OBD I system, as it has a single row receptacle in which to plug in a scan tool, rather than the normal two row receptacles. As the owner/mechanic doesn't have an adapter for such an unusual receptacle (is this the correct term?), he cannot read a fault code on any of his scan tools. Is there a way to "jump" any of the terminals on this receptacle block that will give a fault code by flashing the check engine light? We are stumped on this and could sure use some advice on this first of the Cavaliers. It's a nice car with full instrumentation, fancy wheel covers, velour upholstery, and upgraded suspension system. Thanks very much for any help you can offer.
