Audio problem: When Jesse rings Jane's phone when it's cut off, Jesse is still pressing buttons but there is no sound, despite there being sound when he pressed buttons before.
Suggested correction: He only presses 2 buttons. Anything else is just something like his thumb twitching, like he's anxious or nervous. You see him call Jane's phone multiple times by only pushing 2 buttons.
Continuity mistake: Walter is pulled over by a cop. Before the stop, the cop car is to Walter's right. Walt looks in his wing mirror (driver's side) and the cop car is to Walt's left.

Continuity mistake: Just after Hank crushes Leonel's legs by backing into him, Marco starts shooting into Hank's Jeep. You can see Hank crawling into the rear seat to escape through the side door. But as soon as the camera angle changes to inside the Jeep, Hank is back in the driver's seat and crawls out again. (00:43:30)

Other mistake: At the end, we see the gunfight between Tuco's cousins and Hank. Several shots are fired, cars smash into each other, a woman runs off screaming. So not a "quiet" attack. However, as the camera zooms out to show the carnage, 2 people who are not involved in the attack, are just stood talking in the car park. A bit odd since there has been a very clear shoot out. (00:44:50)
Suggested correction: Nobody is actually standing in the car park. People are standing around on the sidewalks talking to each other about what was going on, keeping their distance. Personally I would keep a bigger distance, but whatever distance they feel safe with.
