Henry Ford intentionally made cars less reliable in order to cut costs (ie exploding Pinto). So I had to learn this stuff. I bought shop manuals (five books) from Ford. Broke the backs of some of those books by falling asleep on them. But I learned - not only about cars. But also about how better diagnostics are performed. And how to read technical stuff.
Therefore as a teenager, I even designed an electronics ignition (with help from Popular Electronics) so that (in today's money) a $100 tune up was unnecessary every 3 months or 5000 miles. And then asked why engineers in Ford could not do that. Damning questions that also taught me how to build an 8080 microprocessor. Not assemble; build by literally soldering every wire.
And learned why failures happen.
Learn all this stuff by doing it - constantly. What I learned about cars also explains fundamental concepts in economics. And so I did not lose massive sums in the 2007 crash.
Simple rules apply. Always discover what failed long before trying to fix anything (using concepts even first taught in elementary school science). Appreciate that nothing works right the first, second, or ninth time. (How many times did I disassemble that carburetor because I had some screws left over?) If doing stuff causes frustration, then one has not yet learned how the real world works.
To appreciate this, find a discussion from Cloud about Idle Air Control Valve. And how so many never bothered to learn how to diagnosis a problem. Many computers were replaced until one mechanic finally did what was obviously the problem.
Some can only blindly do what is ordered rather than also learn what is being done - and why. All that is learned only by solving problems even in other technologies that have no relationship.
First, reasons for his slowness must be defined. Nothing else (no part changes, no nuke 'n pave, no 'try this', and no 'maybe it is that') is attempted. Many never learn how to approach a problem. Then get frustrated.
Read the books that also say why. Never get frustrated. And learn how to think through a problem.
