Emissions? Pfft! I only have those 2 sensors left. The only other vacuum hoses are for the idle controls and the PCV valve

I guess it's time I have to start learning what all the vacuum lines are for, haha - I was always too lazy/scared/intimidated to touch those hoses near the firewall.

I've been looking to do something like that on my motor I'm building up... what did you do to plug the holes? Weld?

And does it throw any codes?

On the DE I believe it throws code 22. For the holes like the EGR valve just cut a piece of sheet metal and maybe get a gasket made then slap that bia on there.

So I was checking out the vacuum diagram today and it looks like one of the hoses that are on the metal thing mounted to the head goes to the fuel pressure regulator. Any word on this?

That vaccuum diagram would be a handy thing to have around, although I haven't needed it yet. I'm sure I will at some point in the future. Think I could get you to send a copy to my inbox?
