My temperature gauge went from cold to hot and then it wasnt even showing anything at all, as if the car was shut off, my car was also shaking a bit and wasnt running good. Any ideas of the problem? And how can i repair it?

Welcome to the forum, what year Mustang do you have ?

I'd start a new thread in the appropriate Tech section for your year car, this section is just for personal intros to the forum. Good luck

But just for a quick check, make sure the coolant level isn't low.
