    blew out my header collector gasket and set off my check engine light. How can I reset the light now that I've fixed the gasket?

    Take it to one of those auto parts houses that check it for free.Act stupid like you don't know what's wrong with it and have them clear the codes.We have Auto Shack down here that does it.

    Or after a certain amount of drive cycles it will go away. Prob a lean code.
