Hello and welcome to JustAnswer!
If the engine controller and whatever components codes are setting for have been replaced and the problem continues then odds are you have a wiring issue. If you're setting a sensor circuit code or something of that nature then and issue with the sensor ground,signal or reference voltage circuit will cause the code as well as the component itself.
What P codes are setting and what specifically was replaced?
