1uz non vvti. running extremely rich on startup!! Help!!

[Gardezi]

Hi all!
My 1uz non vvti's running extremely rich on morning starts or when it's cold. Starts blowing black smoke clouds and runs very rough starts misfiring on low rpms, then goes back to normal when i start driving it over 2k rpm. Idle is also fine then after 2 mins of driving
Only does it when i start it up after stopping for 2-3 hours or overnight.
Any leads pls. Thanks

1. Checked the fuel pressure regulator, it was leaking, fixed it, and it got bettet stopped the black smoke.
But now its doing it again after 3 days after i cleaned the engine bay.

Temp sensor sounds faulty.

The car is loading up the fuel as it thinks its very cold.

Once you get it up in revs it will clear the fuel load and run better but still be running rich.
