I have a question and hope someone can help not sure if its a vacuum leak or a mass sensor going bad but when I start my car up it starts idling really rough bouncing up n down and when I start to drive it I can feel it pulling and kinda jerking not exactly sure what it is hope you guys can shed some light on it thanks

 

Could be several things. Large vacuum leak, bad spark plugs or wires, bad fuel pump or injectors, those would be my first guesses
