ok so i have a 93 s13 coupe auto with 90xxx on the motor i was driving around just now and the car started boging while on the gas i had to give it a bit of gas so it would keep going as the rpm`s droped down to around 450rpm so i had to keep the rpm around 3000 or else the rpm would drop quickly the car has always had problems starting frist thing in the morning or day i think its a gas problem as in the morning i press the gass and pump it then she fires up no more problems i have a narrow band on the car and it read off the guage as the car leaning out yesterday it was rich while on the gas and lean while off the gas spark plugs are not soaking wet iether

I have an extra S14 ECU if that helps. I could probably get my hands on an S13 DOHC ECU if there’s a difference.
