How hard have you been pushing the car???
If it's just a stomp or three,,,and not kicking the crap out of it,,then i'd say where on the right track,,,,Vaccume leaks are gonna create big problems,,,,do the propane test,,,and see if you can track it down,,,and i'm missing something here,,,you said it was idling fine,,,why would you suggest taking off the leads one at a time???

If you cant get sufficient vaccume,,,your carburation air/fuel mix will be out the window,,,also it wont accelerate worth s*** with no vaccume,,it's gonna ping and rattle like an old war horse.
And the smell out of your tail pipe is unburned fuel and if that car has a catalitic converter,,it's going to burn it out too.

As to MSN,,,i do use MSN but i'm one of those guy's who can't hold a beer and type in two screens at the same time,,,,so i try and stay with one.
