My "Check Engine Light" has been on for over a year and it was all due to replacing the Auto Zone gas cap. I did a little research and found this. The check engine light went out a few minutes after installation. If you have a Silverado/Avalanche or similar GM vehicle with gas cap problems, this solved the problem for me.
