Self-intersecting faces issuse

So I’m trying to see the aerodynamics of a Ferrari, and it told me that there were 4 intersecting faces. i was able to delete the first 2, but the second 2 are tiny. like at full zoom they seem to be less than a pixle. i am unable to select or see these faces, and it is still gving me a error. i have tryed isolatong the faces, and i can see them. this is not my model, so i dont know much about these faces. they are near the fron of tha car and almost appear to be in the headlights.
this is my project: SimScale Login

thank you for who ever took the time to read this.
