Coming home from work yesterday I noticed my Service Engine Soon light came on. I got home took a nap and started my car and it wasn't on. My drive to work is 40 miles there and back. Same thing happened on the way to work today and when i went to lunch it was off. Didn't come on, on the way home either. Doesn't the light have to be on for them to check it?
