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

SOURCE: low idle stalls out

Here is the most common cause of surges and stalls at stops and low erratic idle speed and rough idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk over the miles and cause idle issues (stalls, low idle) 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 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.

SOURCE: Car stalls while slowing or stopping

I've had vehicles that have done this in the past. In the meantime, try to get used to using two feet at the same time (one on the gas and one on the break) to keep the RPMs up while slowing down. It's just a temporary fix, and not recommended that you continue to drive like that.

When you have a chance, get a mechanic to adjust the timing 'UP' a tad so it won't stall out.

If the vehicle is at a timing where it SHOULD be, then raising it to fix this problem will also be temporary until the problem can be diagnosed fully.

After all, however, it is an old cheapy right? These are just quick fixes.
