Default Rough idle in drive

1997 4.6, Idles fine in park, when in drive and step on brake it idles rough, stalled on me twice now. Starts right back up. After I drive for a bit and it warms up it seems to be ok. Any ideas?

Try cleaning the fuel system with some SeaFoam gas treatment. You may need a basic tune up

Thanks for the advice, but what I did was replace the Idle Air Control Valve and she runs great. A 40 dollar fix.
