BMW E46 stalls after engine start

Hello,

I've BMW E46 325i. Lately, my car doesn't move quickly after starting the engine.

BMW does move well when I take reverse but when going forward, it goes slowly/really-slow for 100 ft or so and then when i push on gas comes back to normal. This is mainly during starting the engine in the morning.

any suggestion is appreciated.

Thanks,
Gogo

i had something simillar,it turned out to be a dirty fuel pump when left over night dirt setteled and was hard to start and when started ran lumpy until pushing accelarator then would be fine for the rest of the day.
