hey guy`s i just bought a 85 grand national with 150k on it, the guy that sold it says the turbo don`t work, it don`t smoke or anything but the car runs rough(new plugs & wires)and slow. what should check first? sometimes the check engine light comes on and the car wants to cut off than the light goes out again. any suggestions?
Could be almost anything. What is the code when the SES light goes on?
