Question, this ties in with my previous problem but i felt it shoud be a new post.. mods if i'm wrong goahead an move it, no probs.

Anyways.. my supra started really running bad, it sounds like a lawn mower, anything between -10 and 0 vacuum.. there will be NO power, if i'm in nuetral it wont rev past 3000..
When i build boost it runs fine, unless its really bad, it'll take a lot to make it run better.
Now it only does it after i warm it up. So i got under the hood, and revved it a bit, and i can see blue smoke comming from somewhere on the exhaust side of the motor.
WOuld an exhaust leak make my car run this bad? and stay intermintant. It was running fine til i got 3/4 the way home.
