Idk if it is the cause of the problem but I usually keep my EF's obd0. Well in this case I used a jumper harness and the car starts and idles fine but I am getting the IACV code. I was wondering if this is because I am still using a resistor box with obd1 injectors? I know on an EG chassis when adding a resistor box you have to repin the IACV otherwise it will throw a code. Any info is appreciated TIA. - poke.

 

ttt. - poke.

 

no it should work fine like that
