Ground Question

Well, at least you know not to bring it to that shop again or anymore. Always a scumbag out there ruining good named honest mechanics by there actions and greed.

However, with the aid of the layout of the system, chances are you can figure out what the issue is. And of course, yes, we have a good few fellas here willing to help.
