My bf has a 1996 Ford mustang GT v8 and when it's hot outside and the car warms up it will start bogging down like it's not getting any gas but we can turn it off for a few mins start it back up and it will be fine.. it only does it when it's hot outside.. and the funny thing is once it's dark outside and cools off it won't do it at all. The fans do and don't come on they have a brain of their own there is no water in the oil has new coil packs we recently put new injector on it.. does anyone know what this could be
