i had the same problem with my old h/c build and was told its a tune issue. i forget exactly where but had to do with fuel and decel. i blew that motor before i could fix it but ask your tuner.

I would look for a vacuum leak or I would check to see that your IAC is working properly. It also could be a tune issue.
