anyone have pics or another site that will locate the IAC valve

 

Not sure what engine you have ,but its on the throttle body with a hose going from the air intake tube to it, and a harness plug

 

It is on the back of the TB elbow, not really possible to take a pic and a PITA to get to.

Second pic shows it well with the whole TB elbow removed:

If it's a 5.4, see my link on this post.
