Answer 1

For this on a Ford you would have to get the KOER ( Key on Engine running) and do a KOEO (Key On Engine Off ) test to gather the proper code that is going on. There is no sensor that would fail to cause what you have going on with the engine, this is more a mechanical problem with the engine.
