Just to update you guys, this is how the car sounds after 2 junky mechanics (one from this forum) and the stealership trying to charge me $9k for a motor.

You have a steady misfire. Unless it's mechanical, it's caused by blown coil packs, fouled plugs, \stuck injector, wiring issue, or any combination...
Does that 'knocking' sound go away when you push the clutch in? If not, you have either a serious exhaust leak or a bad case of rod knock to go with the aformentioned... my gut feeling is the engine is toast.
Good luck... wish you took it to a reputable VQ mechanic (NOT the dealer under any circumstances) instead of wasting 2k+ and taking ill advice to drive it with a steady misfire...

The knocking does go away when I press the clutch.

The fumes are white, but it smells a whole lot like fuel..
I have new plugs, the first mechanic changed both valve covers and 2 coil packs, the 2nd mechanic changed one injector, gasket...
