Hi Colette, welcome !
I've always wanted a 750il ! acctually, I still want one. and now you have 2 ? :nono: not fair. you'll have to share one with me :excited: ..
hmm, I was researching the 750i once cause I was gonna put its V12 engine into a lamborghini diablo kitcar.. the engine has 3 management systems, one for each side of the engine, and one that controls both of those.. if you lose abit of power, the car could be in protection mode and switched off half the engine.. could be from anything, it has 2 fuel pumps, 2 airflow meter's, 2 of everything needed to run a single side of the engine at any one time.. so the power cuts could be anything, best thing would be to get it hooked upto a diagnostic computer and get the error codes read off, I know zaleonardz is getting a new cable for the E34's in the next few days, I know it will work with the E31, so maybe PM him and ask if he can help u out, I'm quite sure he wouldn't mind. loss of speedo etc.. most likely a wiring problem or wheelspeed sensors or abs unit..
btw, what colour is your car ? ! please post some pics ! would love to see it.. and I'm quite sure the people here wanna see who's driving a 750 also ..
