Should the engine warning lamp be illuminated when is running on a 1995 Opel Astra?
No, the engine warning lamp (often a check engine light or similar symbol) should not be illuminated when a 1995 Opel Astra's engine is running normally. If it's on, it indicates a problem that needs to be investigated. This could range from something minor (like a loose gas cap) to something serious requiring significant repair.
