 (I don't know if the ports have been ported on this engine or not. So they might, they might not)  I'm of the thought that I have alot of little vacuum leaks going on. When I rid myself of the emissions crap I imagine that I'll eliminate alot of the vac leaks.  I'll have to double check the actual numbers when I idle again.
