I have a 1984 crown victoria that had the cfi fuel injection on it. It was goin bad so I converted it to a carb and in the process got rid of a lot of wires and sensors. I can't get the daily reliability I want and am thinking about going to a real fuelie system of a late 80s 5.0. Do I only need a computer and injector harness or would I need to have all the sensors for it to work? Any advice would be appreciated. Thanks!
