Your 1977 Datsun 280Z may not pass a smog test due to several potential issues, such as a malfunctioning catalytic converter, faulty oxygen sensors, or excessive emissions from the engine. Additionally, if the vehicle's ignition system, fuel injectors, or exhaust system are not functioning properly, it could lead to higher emissions. Older vehicles often have wear and tear that can affect performance and emissions levels, making them more challenging to pass smog tests. Regular maintenance and addressing any engine codes can help improve the chances of passing.
