[QUOTE="Flyer58, post: 426342, member: 18629"] I'd still check for engine codes but don't expect to see any because when lights do funny things like that it's usually a bad or weak ground and the current is finding other ways back around through different lights. At that age there's bound to corrosion on every connector and you may want to pull out the cluster/ gauge panel and clean the connections or at least the connector plugs and pins with a spray contact cleaner. That's my best guess [/QUOTE]
