The 1UZ has a cold start fuel injector in the intake manifold. You might want to look up the test procedures for that.

I would first try to give it some a little puch ofthegas pedal to see if it needs more air if it works your Idle control valve may be sticky. if it doesnt help do the fuel pump ECU 12v mod...search it in the forums.and check to see if the coolant injector switch located underneath the top coil pack is plugged in and or has bad wiring. also check that the serpentine belt isnt cutting the cam sensor wires.
