2004 F150 5.4L Triton - rough idle and stall - IWE vacuum leak?

Tyler Sevrens

SOLUTION VIDEO - well.. the way I fixed this problem..


Just posting this for a forum group to view. Truck idles when first started then once it warms up it idles rough and then stalls. In this video you can hear it surge and struggle to maintain RPMs. The video ends because I stopped it thinking the truck was going to just run fine but it up and stopped immediately after I stopped the video. Just.. died. It restarted fine after but idle was rough as usual.

This is pretty troublesome when I'm driving as it surges when I come to a red light and I have to keep the revs up or put it in neutral. Vacuum leak perhaps.. but where do I start looking for it?
