idle problems

Hi, i have a 1990 L98 coupe and im having issues with the idle after the car warms up (it doesnt do it when its cold) but anyway after its warmed up whenever i have to stop say at a light or waiting at the bank my idle surges in rpms and sometimes if its real bad seams like it wants to almost die on me.
Im sure you can guess how embarrassing it is when your sitting at a light in a nice looking corvette and its acting like a volkswagon.
So any help guys would be appreciated,,,,, thx

Hello there -

have you checked to make sure any vacuum sense line to a MAP module is intact, not
cracked, etc? bad data in.... lousy performance out. Just went through this on my C4
