Theres a couple posts in the FAQ about doing this. I did it today, made a huge difference. My truck was idling ok but every once in a while it would stumble or idle not quite as smooth as I'd like.

My IAC was pretty full of carbon, cleaned it out real well with carb cleaner, and pulled the TPS out and drilled the little hole in it and soaked it with electronic part cleaner.

Made a big difference. It idles rock solid steady now and it even seems quieter on idle.

 

Great job!

 

Can you provide links to the FAQ about this, I looked and couldnt find anything?

 

Here's the one for the TPS:

I thought there was one for IAC in the FAQ, but I think it may just have been a thread, that I cant find anymore. The IAC is actually directly below the TPS, its the black one in the pic of the thread about the TPS.

Simply take out the two screws, disconnect the wiring harness from it and pull it out. Spay liberally with carb cleaner, the metal shaft below the dome shaped thing actually retracts into the body of the IAC. Be sure to push it in and clean inside of it and all around it. You cant use too much carb cleaner on it. Just try and dry it and out before you put it back in.
