That would be one of the PCV hoses that I replaced yesterday when it came in from Ford. The other runs from the bottom of the air box to the top, driver's-side of the engine. The filter at the bottom of air box for that hose was full of oil and was disintegrating, so I replaced that too. I also forgot to mention in my original post that the PCV valve & air filter were just replaced in the process.
There is a bit of hesitation when you punch the gas at idle, but the engine doesn't buck when it gets up there in RPMs. However, it dies immediately after as it gets back down to idling speed. Fuel related?
