As I accelerate i notice that my truck does not exceed over the 200 rpm mark. but yet when i step on the gas pedal to drive faster, maybe around 30 or 40 mph, it starts to jerk, not real hard but a jerk that'll make you kinda bob your head. so i step off the gas, it deaccelerates, so i accelerate at a slower or steady pact and it keeps o.k.; until i drive up a hill, doesnt matter how big, it still jerks. i've used numerous products that would clean my engine, a antifreeze gas line, and remove water. it didnt help. i dont kno if its the transmission or if a bought a F'd up truck. so help me out im tired of driving a truck that jerks haha
