My power steering pump bursted into my alternator and shut my car off. I recently changed the alternator and power streering pump but now whenever my car gets around 2.5K rpms or more it’ll shut off and turn back on. Someone I trust read my alternator and said it was overcharging could that be my only issue or is it possible there is more if so what should I do ( also I had my stage 2 z1 tune running when this first happened)
