My 05 545i is acting up big time! The car start and the rpm goes up and down. At one point it drives than completely shut down, not quite sure what it is... from reading through online and forums. I'm guessing these factors: Throttle body sensor, cam and/or Crank sensor? Please help took it to a local mechanic and they have no clue.

Get a BMWhat app with a wifi dongle . Get some codes to give you a direction to point to . It's really hard to guess and give you a significant answer . Due to so many things that it could be . Like a MAF ,Disa Valve, CCV valve, a vacume leak , secondary air hose under the manifold . All those will give you a rough idle . But since you said the car shut off , my guess would be the MAF .
