Easy way to clean IACV
 

I read somewhere there was a tube you could spray cleaner in to ungunk the IACV. Is this true and if so which tube is it?

There's a writeup of how to clean the throttle body and this is part of it, if you do a search you should be able to find it. From my memory it's the hose on the drivers side that connects to the air intake where it connects to the throttle body. There are two hoses there, if you can find the writeup then it has pictures.

If i am guessing correctly, your thinking of seafoam:

You don't have to use seafoam do you?
