I've a slight hesistant within the first minutes each morning. I park the car at work all day and I don't notice the hesitant any other time except in the mornings. It's hardly noticeable, but I'm curious as to what may be the cause.

 

I would like to use seafoam with one of the vaccum hose to clean any corbon built up (assuming it's corbon problem), but I don't know which hose to use. Can I use the hose that's attach to the PVC?

yeah you can use the line going to the pcv valve. That's the one I would recommend as some of the others won't give an even distribution to all cylinders.
