My check engine light came on 3 days ago and got it checked at advance auto.

Please help

If you want to reset the check engine light go to Auto Zone and ask them to pull the codes. When there done with that slip the guy $5.00 and ask him to erase the codes. If that guy wont do it go to the next Auto Zone and repeat step one. Works for me. Boston Mark
