Well I have never seen nor heard of any JDM ECU equipped 2jz needing an airflow meter, just the map sensor..so i dont believe thats the problem..thanks anywaysgood grief... you need an AirFlow Meter... :chairshot
Yea, i initially started it with the JDM 440s and then swapped it out for USDM 550s with resistor,and the problem is still the same. I have even changed out stock regulators. All of the cylinders are firing and all my plugs are dark as night from running so rich...the AFRs stay pegged at 10.0So you went from JDM injectors to 550s and there was no change? Did you pull the plugs to check if all cylinders are fouling out?
