Why do car thieves always try to put in a different engine in each car they stole, and why does the ECU through in funky codes afterwards?

Scotty Kilmer replaced a MAF sensor from a Toyata that was stolen because the previous  MAF sensor on this replacement engine made the car run like crap.  He also pointed out cheap welding and reasons not to buy cheap Chinese crap MAF sensors as it is a critical part of the car. 

What does replacing the engine in a stolen car offer the thieves?

Why would a lazy car thief swap out engines?

Probably because the thieves blew up the original engine.  Car thieves would do that ONLY if they knew how or was not out stealing this week.

why would thieves swap the engine unless they stole the car for the engine to put in another car?
does scotty do any work check out Diagnostic Dan or South Main Auto for how to go about it.

Ain't nobody got time for that. Stolen cars either go to the chop shop and get broken down for used parts or shipped to a locale where no one will ask any questions to be sold.   

Maybe you've been listening to Scotty's oversimplified explanations and annoying voice for too long. If a part is made in China, it doesn't necessarily mean it's bad. It's the supplier/brand at the end of the day that designs or copies the part as well as sets and enforces the quality standards. A lot of aftermarket parts suppliers don't care and this becomes an issue for certain parts like sensors. The same can be said about certain automakers and their parts subcontractors. I can make fun of Ford for cutting corners on their parts and German automakers for making flimsy plastic interior parts all day long.

Who told you that line of BS?! If you think thieves take the time to swap out a motor you're nuts.
