Default fast idle

1990 K2500, 350TBI
I noticed lately that when I first start the truck when the engine is cold it idles a lot faster than it use to. Also after it warms up it is slower to come down to idle when I leave off the throttle. Any ideas would be appreciated.
Thanks

Vacuum leak; probably at the TBI base gasket.
