Now you take one of those guys who knows which is first and ask him if he knows how to diagnosis the dwell I am intimate familiar with (i.e. reading a scope for the electrical signal from an injector) or how to diagnosis a bad high pressure fuel pump just reading the cavitation signal through the sensor using actual voltage not what the computer tells you.

Just because I don't know how to use a matchbook to "tune" a vehicle does not make me less of a professional at my job. Just means I have NEVER had to do it. Ever. Seriously.
That's what makes a true mechanic / tech great, versatility. It use to be called NIASE Certification, when i wrenched, didn't have it, didn't get the good jobs.
What separates one from the other? The ability to Troubleshoot, not just remove & replace, hoping that solves the issue.
