How are you pressurizing the vacuum system? I really want to know more about this… Where and how are you plugging the pump into the system?

I missed the note about WOT, you're probably right. You never know with the AFM though, I chased a rich condition at WOT for a long time and it ended up being the AFM after all.
Check post 13 in this thread, it a has a few pics of the rig I used to find a couple vac leaks.
