It is possible that the idle speed is out of adjustment. Many vehicles from the 1980s have adjustable idle speeds to improve power or fuel economy. I would recommend having the idle speed adjusted to the factory specifications by a qualified professional who is proficient in fuel system tuning of older vehicles. Typically, all that is required for adjustment is turning a screw but it is a delicate process and can be easily overdone or not turned enough.
