Time to replace IAC Valve?

Time to replace IAC Valve?
I was driving to work this morning with the A/C on and noticed that the truck was idling weird when I was at the red light: the RPMs would drop and go back up every 4-5 seconds. I have cleaned the IAC in the past (a couple years ago) because I was having a similar issue when I would shift the truck into park, but it didn't solve anything. Would it seem that the IAC has gone bad and needs to be replaced?

Thank you for the all of the reponses. I'm going to start with the basic maintenance first (replacing the filters and plugs) and then try cleaning the IAC before I replace it. I've cleaned the IAC in the past but it didn't do anything in regards to the stalling issue when I shift to park but I'll give it another shot.
Someone I work with suggested cleaning the throttle body as well, would that be something I'd want to try as well?
