I agree with maytag, check compression (or bet yet leak down if you're able). If those are way off then we will all cry a bit for you. If they check out though it may not be as bad as you think.

With that said, a massive vacuum leak or malfunctioning TB can do this as well. I again agree with maytag that no smoke may be a good sign, and instead you may just have a catastrophic failure along your intake. It's a long shot, just trying to be optimistic for ya. You're obviously not going anywhere with it soon - it may be worth an hour of time to tear down the intake and look at the TB to make sure. It's not stuck open.
