PLEASE HELP! I may be in my own personal Twilight Zone...

I am going crazy over here! Please allow me to set the scene. As a young kid, my sis would watch the Twilight Zone all the time. As I got older I got a chance to obtain them all. Some I had remembered, some I did not. But there is one episode that I can not find anywhere or can not find any acknowledgement of its existence. Not even my sister remembers. This is what I vaguely remember, there was a lady in a car. Somehow later in the episode a guy was in the car with her on the passenger side. As they drove, she told him a story about this other guy that had did something bad to her. They drove a little while and she saw a guy on the side of the road. She told the passenger that that was the guy that did her wrong. She did this a few times and the guy killed each guy. After a while the passenger got suspicious of the woman. That is all that I remember. Does this sound familiar? Maybe it was another old black and white show from that era? Did I make this all up? I am definitely not confusing this with the hitch-hiking angel episode. Please help!
