Not speaking about the OP here, but SO many people want it handed to them on a silver platter and being online, that's usually impossible to do and pretty tough in person. SOME level of diagnosis is required and almost no one wants to do it.
…so sometimes they go Reading and learning sounds boring and slow; why should I bother with that when I've got a bunch of people telling me exactly what part to replace? I'll just pick one of those I think sounds nifty and do that. They waste money and time, their car doesn't get fixed, and they learn nothing. The sun sets that afternoon in the West, and rises the next day in the East. ¯\_(ツ)_/¯
