When Jesse and Mike arrive at the chicken farm they stop behind Gustavo's black Volvo. In the next shot the Volvo is gone, and back in the next shot.
When Walt is playing with the scales in Goodman's office, the low shot has the scales in an unequal position, but when the shot switches, the scales are balanced again.
In the street shot immediately after the "intervention" when Walt is driving Jesse back to his car, Walt's Aztek is depicted the wrong way (and direction) as the car's perpetually missing left rear rim is shown as being on the right side.
