put a jdm h22 auto in a 95 accord auto for a friend. They got him the wrong ecu so I was trying to get it running for him with the stock ecu till they get all this worked out. The car is fine when its cold but soon as it warms up it stalls. It drives fine and shifts but soon as you get off the gas it stalls. with the stock ecu I have no engine light. I tried pluging in the ecu they gave me which has 4 plugs on(car uses a 3 wire harness) it gives me a vtec code and a code 36 which doesnt seem to be valid. Anyone have some suggestions? Im running out of ideas. Im lacking experience with h series issues like this.

I have tried:
New wires
cap and rotor
sparkplugs
swaped iac
swaped fast idle valve
injectors
