I found 2 vaccum hoses dry rotted and one was completely busted open. It seems today its not so rich just not wanting to idle for long. But i still have no engine lite on.

 

that sounds like a sticky or dirty idle air control motor/valve

 

I finally went out and fixed my cutouts and capped them off for street driving. And now its will idle fine, but I smell like fumes..lol Its running a little rich. But I think they had it rich for the nos, to be on the safe side. Anyone ever adjusted that with LT1 EDIT?
