Before reading this....When it comes to explaining things....i could be the worst so bear with me plz.

I just got this BMW *manual* about 3 days ago. It has a "brand new" motor with "1*,*** miles on it"....it looks like to be true (not so smart about mechanics but he is my friend so i doubt he could be lying to me)ANYWAYS when the car is idle it is revving itself up by idk 1100-1300rpms and it continuously goes back and forth revving.
He says (not word for word but something like it) the car has been sitting in the front yard for about 4-5months and since it has a new computer and engine you have to "abuse" it or basically wear it in.
*one other thing is the throttle in the engine (were you can rev up the car while you are outside the car) the cables are loose, like it is missing a piece.*he said he tried it but thats not the problem*

so if you guys know any idea what could be the problem or my friend is right...THANK YOU VERY MUCH for reading this long boring paragraph lol...but lmk plz.

Throttle position sensor voltage is the first place I would look. Google will save your butt with this kind of stuff.
