2000 grand am check engine light
My 2000 Grand Am check engine light came on a couple weeks ago and I had it tested at Auto Zone and they said it was a small leak in the emissions, probably gas cap. So, I had that changed and three weeks later the light came back on again. So, back to Auto Zone we went and it came up the same code again. Small leak in the emissions there's no visible leaks and the gas cap is tight and brand new. Any ideas on where I could look for leaking or what I can do? Thanks!
