A new Beginning..., page-2355

Ever had an opportunity to aask a mechanic how he comes to the conclusion that your car needs to
have a) the injectors cleaned . Or b) the injectors replaced?
I suppose you'd understand it better if he says the diagnostic computer in my workshop has detected dirty/faulty injectors and a heap of crap in the fuel system...
Someone, somewhere had to enter that detail into creating a program so someone else could come up with a software package for a computer to be sold to mechanics all over the world to make their job easier and MORE EFFICIENT. So instead of running the engine, removing the existing injectors and inspecting each one, then putting them back or replacing them, the COMPUTER diagnoses all that and then leaves it up to the mechanic to recommend action to you, the owner...
OMG... is that basic or what?
I wonder how many car owners went to another mechanic for a second opinion?
