During the car chase between the heroes and the weasels in Who Framed Roger Rabbit, the weasel driving sneers "I'm gonna ram 'im!"... then, when the attempted target of their vehicular assault dodges, he and his mooks scream as they hurtle towards a crash, just like the scene with Biff chasing a skateboard-riding Marty in Part II.
In Dark Future, Bronson Manolo's high-tech and highly secure tank and mobile command center is a DeLorean Sand Master.
Stop me if you've heard this one before: The male protagonist of a Time Travel story falls in love with a girl whose (married) name is "Clayton". Said Time Traveller also funds their stay by gambling on longshot sports upsets with future information. Guess what that description applies to?

The description for the "Guilty Pleasure" home video says that the label gave them $650,000 to make the video, which they blew on a sports car. Afterwards, the official video for "Guilty Pleasure" was released, and we get to see that the car the band blew all that money on was a DeLorean.
The music video for the Electric Six song "Down at McDonnelzzz", a DeLorean shows up at one point.

Also, an encounter in the Haunted Ballroom mimicks the plot of the first movie, the difference here being that the Marty stand-in is a ghost, like everyone else there, and therefore isn't really in danger of death. Nonetheless, the player character helps him out. (As an added bonus, the filename for his image is named "Keaton.jpg".)

Then there's this discussion:
Dan: Marty gave this random black guy the push he needed to succeed in 1955, the year the civil rights movement started. Katie: (bewildered) Okay...so you're saying...? Michael:Black people invented hoverboards! Dan: Close. I'm saying I wouldn't be surprised if the original rough draft of Back to the Future was Marty time-traveling and crafting black history. [gives examples] Michael: I would watch that movie. Dan: All I'm saying is that Marty influences history in exactly two ways, not related to parental boning. One, he gives black people the idea for rock music. And two, he gives a black guy political aspirations the year the civil rights movement started. Katie: (conceding) Okay... Michael: Huh. Why do you know what year the civil rights movement started? Dan:Why do you not?!

Steve climbs out onto the hood, leaps into the other guy's DeLorean, steals the knob back, and then jumps back to Stan's car, even flipping back down into the passenger's seat. All while a Suspiciously Similar version of the Back to the Future theme song plays.
The Family Guy episode "Meet the Quagmires" is a Whole Plot Reference to Back to the Future, with Peter going back to 1984 and accidentally preventing his marriage to Lois.
When the twins travel into the past in an episode of Gravity Falls, Dipper asks "When the heck are we?" Mabel is about to ask the same question. This is a reference to the first film, where Marty asks "Where the hell are they?" and Doc Brown replies with, "The question is, when the hell are they?" Dipper said the line Mabel was about to say, as she expected him to start with, "Where the heck are we?", thereby copying the exchange word for word.
