You have changed all the things that have no effect on the root cause of P0172. You need a new Fuel/Air Sensor. Your ECM is showing that the fuel air mixture is too rich, so it is reducing the fuel that is going into the engine. That causes the ECM to compensate by running the engine lean and that causes overheating. Buy a Denso sensor, they are the best.
