I've got some code on my civic, I swap a b18b. And the code 71, 72, 73, 74 is on and it looks like a missfire. So I changed my spark plugs, my spark plugs wire, my distritutor, and it's still doing it. What can it be ?

 

check your spark plugs firing order. and also u didnt over tighten the spark plugs,right ? can your car fire up ?

Dont forget to reset the ECU as well when you are done.

 

no the spark plugs are not too tight and the car is running perfectly ! I also reset the ECU a couple of times now...

if the car is running perfectly why it is throwing the miss firing codes? and also what ecu are u running ..and what kind of engine ?

 

it's a b18b from japan (92)b18b, and the ecu is an original one coming from an integra 94b18b1. Maybe the computer is not good for it ?
