Murilo EJ1

My B16 swapped EJ1 is showing some odd behaviour. I've made a thread on this before, but didn't get much out of it.

Anyway, when cold starting the car, the engine does one of two things:

-Stalls immediately after starting. Also worth noting that if I give it some gas, and hold it at a steady RPM, the car won't stall if I let the pedal go after warming up.

-Stalls after the smallest throttle input (however, it doesn't stall if I let it warm up)

The car pretty much starts and idles normally when warm, but is a nightmare when cold. I have to sit in it for some minutes every morning while it warms up, and it's a pain in the ***.

Throttle cable, TPS, IACV and Fast Idle valve are all in order.

Check timing?
someone with idle issue, a few thread down, said his was the timing mark on the crank pulley were set incorrect.
try that

Stock ECU ?

Check the two pin temp sensor under the vtec soleniod
If the ecu is not seeing the correct temperature it could be dumping fuel
