ive never had this problem until i started my car on a cool temp day and released the clutch abit too soon and stalled it. i tryed starting it again and it seemed flooded. my car's an S5 so i pressed the gas while starting and after 2 of those, i tried again and it started fine.

ever since, when its cold or hot, ill crnak and the engine will seem like its either drowning in fuel or not getting enough fuel to start at all. i havent had the cold start assist kick in since i stalled it (2 weeks now).

my compression's goold, i idle at 750 and the car runs very smooth.

what could it be?

 

you should probably check your engine
