Ok heres the problem, My wife has an 1983 4.1 Seville It started smoking(rings) and was running real bad at idle and had NO POWERthe motor had a gozillion miles, motor change was in order found a low mile Eldo 38k to be exact that was totaled done the motor swap now the problem begins the car still runs like crap, stalling , no power, I have tried giving it timing has great fuel presure, new tune up. I am at my witts end with it .I know when I had the motor out the wiring harness had some bad wires which I had repaired but I thing the harness might be the culprit and the harness in the Eldo is worse but it ran great so any input would be GREAT , I Told my wife that she might want to say good-bye to her big girl she will have no part of that she wants her car fixxed soooo. I have got to get this car fixed my well being depends on it
