Maybe I am old fashion, but I think that auto repair should be auto repaired. So many times we take our cars to a repair shop only to hear, “We have to start with this and hope”, hope? Why not fix! With the level of computer intergration, most vehicles self diagnose. If a shops says this to you, look out wallet! They are telling you they are not sure whats wrong but if you don’t mind footing the bill, we can throw enough parts at the problem until it goes away. I know some problems are difficult to find, but dilligence can be a money saver. The key to getting a direct answer to “What’s wrong with it” is really a 3 pronged appraoch; 1) Technical knowledge 2) Tools 3) Technician. If you have these things going for you, there is a good chance you will only pay for the repair and not that shops training session on your car.
