Lost Knight - S3-E10
Plot hole: The explosion strength of the XPL nitro-plastiqe is very inconsistent. In the opening scenes, six cubes are enough bring down a building. Later, Bobby throws two cubes of it out the passenger window. Oddly, they end up on opposite sides of KITT, and then cause only very minor explosions. In the next scene, Bobby throws the another two cubes of explosive out the window, and those explosions are enough to collapse a power pylon. (00:08:26 - 00:08:49)

Continuity mistake: The red wagon has Bob's plumbing painted on the side of the driver's side door.When being chased by Michael Knight, the sign is missing. It reappears later when Doug is playing inside it.
Lost Knight - S3-E10
Plot hole: KITT loses his memory of Michael and Bonny gives Michael a new memory to replace his damaged one. Now this is a back up version and improved memory. But after the old backup is restored, KITT still knows who the boy is, despite meeting the boy after that backup would have been taken.
Answer: I would say that unless there's visual evidence it was another K.I.T.T. car, as in you could see the bar scanner or cut steering wheel, people on here would correct the mistake by saying more than one 1982 Pontiac Firebird Trans-Am was sold and there's no reason it's meant to be a random car.
