'05 Durango is rough idle at stops and sometimes almost dies out. I suspect the IAC valve from lots that I have read here. What I can't seem to find on here is a picture showing me the location of this part so I can replace it. Can anyone provide a picture or diagram as to the location of this IAC valve on the '05 4.7L engine?

Thanks!

 

It is directly below the TPS.



#2 is the TPS, #3 is the IAC.

 

Thanks!!

 

One more note... your IAC may or may not have two bolts holding it in. On the 2006s, its only one, the one shown in the diagram closest to the front of the engine is not there.

 

Yes mine had only one screw.

Now that I have the new one in, the truck seems a little better but still not as smooth as I would expect it to be while stopped at a light or something. However it doesn't die any more.

 

Next thing I would look at would be front O2 sensors and check for the infamous 4.7 exhaust leak/broken manifold. New front O2 sensors helped a lot with my wife's rough idle issue, and now its just barely there at stop lights/signs. It does have a loud popping sound coming from the rear exhaust manifold area when cold started, so just gotta wait for some money to fix that.
