Question about 1999 BMW 323 Series
It sounds as though you either have a faulty O2 sensor, or there is a fuel pressure issue, which from your description, could be due to a worn fuel pump.
If the car performs ok under full acceleration, but plays up at either part throttle or no throttle, then you may well have a faulty O2 sensor.
Very best regards
