There is a idle air control sensor that would need to be pulled out and cleaned along with the throttle body, and that port the IAC Valve goes into. It is best to take the throttle body off so you can clean under neath that port. May want to replace the base gasket also, for the TBI. It is located on the right back side of the TBI.
