I concur with Turbo on the black smoke thing - better being black smoke rather than white as it should be a rich fuel problem, not a burning oil problem.
I would check your MAP (Manifold Absolute Pressure) sensor as if this has died or the wire or vacuum line has come loose/broken it will run like a hairy goat and blow heaps of black smoke.
When I replaced the head gasket on my previous car (EF Farimont) I forgot to put the vacuum line back on it and it ran like yours sounds. At first I crapped myself and thought I had put the head back on with the timing out 180 degrees because it sounded like it was firing on 2 cylinders! Noises from the engine didn't sound too good either....
