MY son has a 2003 Alero, check engine came on so he went to Auto Zone for a free diagnostic, code read catalytic convertor, we replaced, done! My engine light has popped up on my 2007 XLR. I don't believe it's gas cap and car seems to run fine. Question, can Auto Zone accurately diagnose my XLR light or do I need professional help? (for the car, haha!) Thanks.
