sounds to me like it's your idle air control. Pull your throttle bodies off and you'll need a new gasket to put it back on, don't try to reuse old. on the side of the throttle body is the tps (throttle position sensor) and the IAC (idle air control). both have electrical connections on them. The idle air is a plunger that usually gets very dirty over time on the plunger and needs cleaned, along w/ the throttle body. It controls your idle. You may be able to get it out w/out taking throttle body off, but wouldn't hurt to clean up the throttle body too while at it.
