Continuity mistake: When Christine is fixing herself after the guys smashed her up, her front end is shown to be perfectly straight for its entire width and the hood is missing. Near the end of the scene, the front end is shown crushed and unfolds again, and the hood appears from nowhere.
Visible crew/equipment: After Calvin Bouchard makes the announcement to tourists visiting the Undersea Kingdom to evacuate, we see the tour guide lead the crowd through the tunnels. The green screen backdrop is still in the final cut. They forgot to add in the underwater effect.
Visible crew/equipment: When Dr. Raymond leaves with Mary in his car after talking to Norman, when he drives off the entire crew and equipment can be seen reflected in the side of his car. (00:41:50)
Visible crew/equipment: When the telephone rings, Cujo bounds over and begins barking at it. After he has finished barking, he lingers in the window frame, and then, you can see a crewmember's hand come in, and pull him down from the ledge. (00:55:30)
Revealing mistake: The outline of the blood pack is visible under John's shirt when Stillson's body guard shoots him. (01:37:35)

Plot hole: It seems unlikely any mental institution would let a patient out to visit home for any length of time as happens in the movie with the killer and his mother.
Suggested correction: Unlikely, but still possible. Almost every workplace has a situation in which a person is bending the rules.
