Serious Issue

[Yiddie]

WTF!?!? Did a boost leak test found out I had an air leak coming from my throttle body, Got new oem gaskets, fixed it and now my car is running like shit! Idles rough and when I rev it, it sounds like its missing and somehow magically now I have white smoke coming outta my exhaust manifold area and muffler really bad.... No idea how i could be burning coolant from just taking off my throttle body and the part that is attached underneath the throttle body.

Any suggetions....
