Continuity mistake: Mike's car is not visible when Walt breaks into his own backyard. Mike is still there, as you see him hiding behind the corner, and later getting into his car.
Continuity mistake: When Emilio's body crashes through the ceiling and lands on the downstairs floor, there is one huge chunk of carcass that lands on the floor in one piece.

Continuity mistake: At the end of the episode when Walt and Jesse are leaving the junkyard, the camera pans to Tuco and Ganzo watching them drive away. However, this is at the same time Ganzo is moving No Doze's body and is subsequently crushed by a car.
