On my phone and it likes to send before I am done typing..

Yep you need to get it fully warmed up and burn off any residue in the exhaust. A simpler way, not really simpler, better way to rule out stuff in the exhaust is to remove the intermediate pipe between exhaust manifold and cat. If you are getting water vapor still it has to be still being introduced to the combustion chamber.

Pps

Pretty common mistake is hooking one of the coolant lines to the iacv into the intake (we see this more on the 3vz than 22re) but it is worth the few minutes to check the vacuum and coolant lines go where they should.

UPDATE: It works perfectly now. Needed to get it up to temp so I could burn off the old smoke. Thanks so much for everyone's help! I owe all of you a beer for sure.

Nuff said.
