You will need to run some tests..like pulling codes,fuel pressure check etc.Anything to give the viewers a better idea of whats going on.I'm going to take a shot and say its either a vacuum leak.. a coolant temp sensor(CTS) or throttle position sensor(TPS).How does the car run when warm?Without any more info you'll get nothing but maybe its this or maybe its that.
