Your best course of action would be to replace the Air Control Valve with a new unit. It's a pretty easy job to perform by even the greenest of shade tree mechanics. I'll even be a sport and post up the procedure for you
1) Disconnect the negative battery cable.
2) Detach the wiring harness from the IAC valve.
3) Remove the two retaining bolts. (ref #27 & 28)
4) Remove the IAC valve (ref #17) and discard the old seals or gaskets.

6) Using new seals or gaskets, position the IAC valve on the throttle body.

10) Connect the negative battery cable.
