740il engine problems HELP!!

hello all. i am new to the bmw world but am a mechanic. i just purchased a 1998 740il and the engine idle fluctuates and when i rev it one time will rev fine and the next time will rev very slowly like it is starving for fuel, i am thinking MAF sensor but am not sure, please lend me your thoughts. thanks
