a bad engine
The car shakes because your engin has been cold and you sudenly start the car it will shake
check motor mounts
Engine mounts
its not spossed too...you may need to balance your tires
The engine of the car may need to be cleaned or your oil may need to be changed.
Possibly front end is out of alignment.
As I remember ^^ Because once you start the engine you give it power so it start working, and this power is really so HIGH that your car can start from 0 MPH to 100 MPH or something like this. So for sure it would shake.
your problem is yu have a broken motor mount that will make the car shake when you start it and step on it
