Plot hole: At the end of the film Shaw and Dom drive their cars onto the plane and the pilot says they are too heavy to take off, but Shaw's team consisted of an extra car, which the plane was clearly prepared to take off with.
Plot hole: There is not enough time for Dom's team to prep the cars for Europe that Parker brought at auction, adding winches and roll cages etc.
Plot hole: When they have to let Shaw walk out with the chip because he has Brian's family hostage, he walks past all those soldiers and drives out of the base. He tries to use his phone but the crew blocks all signals in the area so they can chase him. We cut back to everyone in the army base and the army have just disappeared, leaving it up to the team to chase Shaw down a runway alone. (01:39:30 - 01:40:50)
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.
