I have a 1989 volvo 740 gl it drives fine as long I don`t exceed over 45 mph. Once I get up 50 or 60 mph it starts to jerk and cut back real bad. I have replaced the fuel filter,plugs,distributor and the rotor and it is still doing the same thing. I have reach 70 mph and it stop jerking and cutting back.
