Continuity mistake: When Luke gathers the whole team he throws Owen's photo on the table. In the close-up it lies next to a colour brochure, but in the wide angle it is a totally different type of paper.
Continuity mistake: Luke finds Toretto who says "I wasn't hiding" and raises his right arm to fix an engine. A shot later he is further away from the engine plus his arm is lowered.

Continuity mistake: At the shoot out, Gisele is talking with the wounded man who made the gadgets. He has a small amount of blood spilling out of his mouth, down the side of his cheek. A couple of shots later, the blood is now a long streak down his cheek. Then it is suddenly just a tiny smear of blood around the edge of his mouth. (00:46:20)
Continuity mistake: Roman removes a 100 Grand bar from the shot-down vending machine. In the close-up shot, there are several other 100 Grand bars visible.

Continuity mistake: When Hobbs says "I'll sort your transport out for Spain" it cuts to a Hercules transport plane. We can tell that the rear ramp is down as we can see the support struts, but the inside scene shows none of the effects of having the ramp down while flying.
Continuity mistake: During the fight on the bonnet of the land rover the bullet holes in the windscreen appear and disappear between shots.
Suggested correction: That's exactly the problem that Shaw is referring to, a member of his team installed the incorrect plug which caused a problem, i.e. a Spark Plug and not a Glow Plug (a simple thing, causing the problem), along with the 'good' being simple minded and causing the rest of Shaw's team a problem.
The glow plug isn't what causes combustion in a diesel like how a sparkplug does for gas. The wiring harness for a spark plug vs a glow plug is completely different and they aren't interchangeable. You can't just accidentally put a spark plug in a diesel, it doesn't work like that.
