A check of the operation of the throttle position switch is first on the list.

Check your air hose for splits and tears.

i had the same problem, after speaking to a bmw expert he told me to adjust the airflow meter, i did so and all is good now.

Air meter bypass should never need adjusting. If you adjust it and it improves things, then you are just masking another fault.

In the real world, adjust it, and don't worry about it.
Needs to be set up on a CO meter, though.
