When driving the car for a while the car starts acting like it is out of gas and trys to run hot. I have replaced plugs, wires, head gaskets, mass air flow sensor, fuel filter, cadilliac convertor, and air filter. When put on computer it just reads firing problems but coils and cols pack is good. I have no idea what else it could be. Do you may know what's wrong?
