Are you talking about the (orginially) made for TV flick? The anthology film from the 80s?
One segment was about a killer in the backseat of a womans car. Another involved Emilo Esteves and a video game. Then there were two others, one involving a preacher and a truck driven by Satan and a house infested with giant rats.
If that is the one, then the name is Nightmares. Check it out at
www.imdb.com. You should be able to find a copy of DVD pretty easily.
