How do I reset my engine light??I had a bad plug that turned the light on, I changed it and a week later the light is still on....

please include your year/trim level in your signature so we know what kind of car you have.

Autozone or any other parts store should be able to clear the codes for you if you have OBD2, which is 96+

If you have a 92-95, just disconnect the battery for 10 minutes and it should clear it.
