Once you've got it out, take some TB cleaner and clean the junk off the plunger. Then spray some in the TB where the IAC goes in and take a rag (lint free) then a Q-tip to clean out the port. Install the IAC and you're done. Cheers.
Ok I took it off and cleaned it and the port it goes into and that seemed to help. It idles fine then if i give it some gas and let off the gas it act like it wants to stall the rpms go under 500 then back up to 600 where she is idling. I sprayed carb cleaner into the throttle body and that seemed to help more than cleaning the iac... Is there something in the throttle body that i need to clean too or what else could be causing it to die only after I give it a little gas.
My van is not the one pictured in the article. I did take mine apart and clean it, but it was more of a preventitive measure - it ran fine before I did it and it ran fine after. Mine was fairly dirty, but aparently not bad enough to cause a noticable drivability problem.
But I would imagine that if the change from dirty to clean is drastic enough, than yes, the PCM will likely need a little time to adjust.
