Well, I almost killed TAV if he would have been under my car when he told me to start it up. He was Checking for a rattle sound and found it. He car was on two jack stands in the back. He told me to go inside and start the car. I do not put the car in 1st when I park. He does. I didn't check. So when I cranked it the car pulled forward and almost totally off the jack stands.
