Preach! I was long in the habit of replying to "HALP MY CAR IS BROKEN EVEN THO LOOKIT ALL THE PARTS I'VE REPLACED!!!1!!!1!!!" posts by advising a stop to the money-spending and parts-throwing, and coaching on how to diagnose what's causing the problem(s). If I'd been keeping track, it would be many years since I lost count of times I've been told off and bіtched at for it.
