BOSCH or BREMI

BOSCH is good through right?

Sorry, I have a LCI facelift 2004 3L. Of those choices you listed, I would go with the Bosch not the Bremi especially for only a $15 difference.

Yes, I believe it should idle with MAF unplugged, I have seen guys running their E46's unplugged for weeks but again, I do not know the 2003 4.4 system to give you a solid answer. I would look towards an intake leak somewhere in the system causing the stalling but get the new MAF installed and go from there.
