1st clean up the throttle linkage and make sure the butterflies are closed all the way. clean up the throttle body. if that dosen' t do it then try these: iac stuck open, tb gasket leak, if you still have the original plastic vacuum lines check all of them or just replace them with all rubber. tps out of adjustment.
