Car stuttering

When i start up my car and speed up at around 5-15 mph the car will stutter very hard as if i’m running over something and when i slow down using the brakes it does the same thing. This only happens the first few minutes that i drive the car. I have a BMW 2014 328i rwd

Your vehicle’s stuttering problem could also be caused by a faulty throttle sensor. When the gas pedal is pushed, the malfunctioning sensor does not send information to your engine’s computer accurately. If your throttle sensor is failing, other symptoms can include hard starts, rough idles and poor fuel economy.
