Hi there. When the battery was arched, the power surge had went through the vehicle and caused some circuits to fail. If right after the power surge happened and now you have a code for the fuel pressure and the turbo, I recommend replacing the fuel pressure sensor on the fuel rail and the barometric sensor on the intake. This should take care of the idle issue and the cut outs along with any problems with performance issues. If you need further assistance with your engine stalling after arching the battery, then seek out a professional, such as one from Your Mechanic, to help you.
