HELP! 02 X5 vibration and stalling in the morning in reverse or drive

[02BMWX5]

OK first of hello and looking forward to learning about my X5. This is my first time posting a question.

I have a 2002 X5 that in the mornings when I start it in the garage and back it out it vibrates and acts like it wants to die.

Sometimes it does die and even if I put it in drive only in the driveway

Once it warms up it runs fine and no issues

The dealer put a Idle control valve on it and it did not fix the issue

If I am out driving thoughout the day it does not act up only on early morning starts

No codes and no check engine lights at all

Any advice

Thanks in advance I do not have the money to keep guessing

Maybe due to bad Vacum?
