Recently bought this car for my wife. All orignial and to the knowledge of the previous owner the car has 96K and no indication of engine ever being rebuilt. Previous owner did a tuneup. New plugs, wires, cap/rotor, PCV and air cleaner. It starts everytime and runs ok on hwy. It does bog down sometime when I stomp on it to get out n traffic. Also will not go past 80-85 seems to cont. Being sluggish at that speed. HELP!!!
