A master tech in Detroit called my diagnostic process lazy, and he was right
Honestly, I still think about this one guy I worked with at a shop off Michigan Ave in Detroit about half a year back. I was chasing a random misfire on a 2016 Silverado and had a scanner pointed at cylinder 4, ready to swap a coil. He walked over, unplugged my scan tool, and hooked up a vacuum gauge to the intake, saying if I trust live data over a $30 gauge I will be guessing all day. Turns out the intake gasket was leaking, a 45 minute job, and I had already sold the customer a coil and a plug. Ngl, I felt like a rookie even though I have been turning wrenches for 9 years. He did not say anything else, just handed me the gauge and walked off. Any of you guys run into an old timer who makes you rethink how you do diag?

Doubt he unplugged your scanner, he probably just told you to grab the gauge instead.
