>>16445473>Car mechanics don't care enough about you or your shitty vehicle to bother breaking your vehicle. They just want you out of their face as fast as possibleThis.
Also, while they may notice the other issues, often the service writer will tell them to shut up and just fix what they are told to fix.
And "yes" a lot of younger mechanics are little more than parts changers. Most have no real concept of how modern engine controls work, and do not know how to troubleshoot driveability issues. if they cannot have the scantool tell them what is wrong, you'll see them loading the parts cannon and blasting the customer's money all over instead of actually fixing the issue.
