ok i have a 90 da with a b16 i just put in about 2 months ago at first it was getting good gas mi just over 300 pretty good i think and now it has droped down to less then 200 what gives i cant figure it out my ecu is not throwing any codes and i have a little spuder at low rpm and im only getting a little over 200 mi per tank i dont know what is going on…
thanks justin
Have you checked the obvious things like cap/rotor/plugs/wires?
yes when i put the motor in i put new cap, rotor, plugs, wires ,oi,l oil filter, tb cleaner my little bypass thing that goes from the intake to the throdle cable broke and i have been running around with it off and someone said that could do it so i replaced that today its just down to o2’s or injectors i think??
sounds like your 02 sensors are bad, replace them it couldnt hurt. replacing those little bastards on my b16 is probably the best thing i’ve ever done to it.
yea I get the same gas mileage replaced everytihng except the o2 sesnor maybe its time for a change lol.
