My car just had a tune up i took it to auto zone for a diagnosis and was told something about gas cap my check engine light is still on
When the check engine light is on, it means that the ECU has detected a malfunction that will affect emissions. In your case, if the Auto Zone guys suggested that the gas cap was loose, then you may have had a P0440 code. Which might indicate an air leak in the fuel vapor recovery system.

They can send a technician to your home or office to check out your Nissan and make a recommendation as to how to fix it.
