SOURCE: 2000 323i stalling when i slow down
Here is what you need to do, a cleaning of the intake throttle blade and the idle speed control air-bypass valve, they get full of gunk over the miles and cause idle issues (stalls) like yours,
Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the engine at idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake

Sounds like a bad motor mount, pop the hood and see if the motor shakes or moves rapidly when u put it in gear holding down the brake.

Hi! You definitely have a faulty MAF (mass air flow) sensor. The MAF has big contribution on engine performance specially the idling. Once the MAF is replaced you'll be good. Hope this helps and have a good one!
