Recently, when I start my buick, the engine sounds like it's about to stall, drop down to about 100 rpm, and then rev up to about 1500rpm and get back to idle fine. The car idles and drives like a champ afterwords, but the initial start is strange. Any ideas what it could be?

Dirty IAC? read these sites for cleaning & how to set it properly Vortex Buicks

Surprisingly, I think the IAC cleaning did the trick. It didn't seem that dirty, and the IAC is only a year old. But I guess even a tiny layer of carbon is enough to screw up the starting. Anyway thanks for the help everyone.
