I'm hoping that I finally found the solution to my SES light. I went ahead and changed the pcv tubing for another one straight from ford.. Here are the pics of the one I took out. I went ahead and put a cobra pcv valve also. Im now on the waiting process cause it takes about 4 days for the SES light to come back on.. Im hoping its over though

 

Looks like you found ur problem. Id say that cracked hose is what drove you crazy.

 

Where exactly is that hose located?

 

Nice detective work! Was the cracked hose the one that goes to the rear of the lower intake??

 

Yeup. This hose goes to three locations. The one that was cracked was the one that goes to the rear of the lower intake. What a PITA to change without taking anything apart. It wasn't really cracked but it was flat and rotted, it broke when I took it out..

 

HOw do you get to the bottom of that hose to replace it. Mine has some cracking at the top by the plenum. Pull the blower??
