Q: Loud cranking, shaking, RPM decrease upon start - 2004 BMW 325is

asked by on

The car has been making loud cranking sounds lately. This occurs when I start the car. It would also start shaking. The dashboard has been showing the RPMs slowly decreasing too. I'm in fear that this might damage the car badly, so I only start the car and let the engine run briefly. How serious is this problem? What should I do?
