idle surge...stall?

[m3outtanowhere]

when I'm crusing and put the clutch in the rpm's to 200-300...sometimes it stalls? is this the idle control valve. car runs fine?

ok. so i checked the search bar and did this: cleaned inside of all intake system (filter, boot, manifold, afm). I found the sensor inside the maf bent and touching the plastic surrond. so i carefully straightened it out and put it all back togeather. The rough idle is gone! BUT when i brake hard my idle still drops! so i pulled over and pumped the brakes really fast, and the rpm's dropped to 150 or so! i tapped the gas and it idled fine. pump brakes...almost stall. This leads me to believe it is a vacum leak. DOES ANY ONE KNOW WHERE THE LEAK IS COMING FROM?

I don't think the fuel pump was the preblem of this, i think is time to ask it to Super Dustent he is like SM (super Man) but to him means Super Mechanic, beleivme he want to help
