I was doing some maintenance to a recently purchased loyale and pulled the throttle body off to clean and check the throttle position sensor.

Put it back together and now it's pouring white smoke  out the exhaust. I did not change any gaskets, is it possible that coolant is leaking into the intake from this? I didn't think I saw any  coolant lines going to the intake there but maybe I screwed up. 

Yes, there is a coolant passage in the manifold, directly under the throttle body.   There is a special oem o ring that seals it.

Sounds like spfi

you need a toilet bowl gasket!
