I have a 87 Grand Fury, 71k on the ticker. Problem had kicked up. When the car reaches operating temp she bucks and kicks like a angry horse. I have checked all the conections everything is on tight. It just started doing this.. It makes the car undrivable. The car has had new plugs, wires, cap rotor and the carb rebuild. Anyone???? Thanks Jake New Hampshire It has the 318 with carb.
