Thanks for the Reply Ross.

I actually doubt I have *that* much idle time on the car. Probably more like 5 hours. Idle time is mostly just because I still have body panels off of the car and other projects going on, so yet to really get it on the road.

I think you might be on to something with the vacuum pump. It looked to be a fresh rebuild, but has been in a hot and dry environment for ~ 4 years, and on a shelf for who knows how long before that. I quickly took the tube from the fuel/vacuum pump to intake off and noticed some oil on the on the fuel/vacuum end of the tube. Nothing excessive, but I am assuming there should be *no* oil.

I would guess a diagnostic test would be to pull a vacuum from the inlet and plug the outlet and make sure it holds (I am sure that there is a diagnostic test in some packard literature one of the gurus could post)?
