Hello Amanda- my suspicions are that this an ignition or an engine management system problem- the 1st thing you should do is scan it for diagnostic codes-also have the fuel pressure checked- the most likely suspect is the crank shaft position sensor- but it could also be fuel injection or ignition coil problem- thanks Super Girls Auto.

There could be a number of different possibilities causing these symptoms and they may or may not be related. You could have a fuel delivery problem, a low charged battery, a broken motor mount... In order to diagnose both problems correctly, you will need to bring your vehicle to a qualified technician that can at least visually check the vehicle.
