2004 Hyundai Santa Fe. Lose of power!!

Question

My Santa Fe has the 2.4 and 5 speed manual!! It will not pull it's self up a hill. It also will not go over 60mph!! If I push down on the gas to far it starts to jerk!! There is not light on!! It also has a little shutter at idle!! It seems like it is flooding or not getting gas!! It starts right up!! It also will not rev over 3,500rpms in neural!! If you have anything that can help I would think you alot!! Robert
