Car shut off abruptly?
While leaving my college class I turned my car on to hear it struggling to stay on, basically running but chugging along as if it was at 500 rpms or so. I revved the engine and the car made a tinging noise like someone dropped a metal wrench in there and it was bouncing around. I attempted to drive home so I could do research and go get replacement parts but it started losing speed while still "accelerating" then just shut off. The engine didn't sieze because it will attempt to turn over but just a bunch of smoke pours out. If anyone has a solution that would be wonderful, I had a tow truck bring me home and I need to fix it as soon as possible.
