Have a problem with the 750li bmw, when starting it appears that the gas is taking a minute to from the tank to the injectors, thus causing a rough start each time. What do you think the problem is ?
Possibly faulty fuel pressure regulator or dirty/faulty idle air control valve.
Could also be a vacuum leak.
