My 1989 ford f250 efi 460 motor was running great then I moved the negative battery cable to a better spot other than on the factory mount on the exhaust manifold, now it runs very rough, misses badly and barely runs. What did I do wrong? Or is there something else? I have previously replaced the plugs, cap, rotor and wires, battery is new also.
