Help engine dies and white smoke from back

Hi I'm Lee new to this forum.

I have recently bought a 2007 cx7 2.3 turbo but am having engine issues. I was told it was coil packs so I replaced them along with new spark plugs and still problem not solved.

I then changed the air mass sensor yesterday and still have the problem. The car starts but as soon as I go to rev it the engine dies and have white smoke from the back. Does anyone have any idea to help me please as it's really annoying me lol.

Thanks guys
