1991 acura integra- swapped with a b16a/b17 trans timing was on and has new wires/plugs/cap&rotor.new mounts all fluids are fine. the car studdars from 1400-2000 (jerks in and out not through out the whole rpm) but starts again at 2500. But under heavy acceleration it dosent jerk. we thought maybe spark but everything is basically replaced but the distributor and if it was a pump or injectors wouldn't it have trouble accelerating or be jerking from idle (idles fine and smooth) Had a mechanic friend mess with it a little couldn't figure it out but after he was done my car wouldn't jerk or stutter but it wouldn't get pass 2500 rpm no matter what you did so i disconnected the battery and its back to the old problem i really need help its near imposable to drive like this
