I have a 98 b18b in my civic coupe and I'm having a misfire issue.

Basically whenever I start the car after it was been warmed up (and sometimes on cold starts) the car misfires and it goes away once I start driving it which is kind of strange and doesn't ever misfire again until the car is turned off and back on. I changed the plugs so far but what else could be the problem?

 

Take a look at your cap and rotor, maybe they need to be replaced, also if you have access to a timing gun, check your timing too.

 

I would think that the spark plugs wires are bad. Just pull some off of a friends car, and try it out.

 

i have the same problem but a lil worse underload the car seems like its runing on 3 cylinders. i change my entire dizzy plug wires and the plugs and even the fuel filter and i still have the problem

 

i had a smiliar problem and i tried, dizzy, cap, rotor, plugs. wires, fuel fitler and none fixed it i fixed the problem by replacing my o2 sensor so try that also...

 

o2 sensor is most likely the issue if u have tried the distributor.. usually a dsitributor wont do that.. they'll just go out.. but sometimes they act up a lil first.

Good luck

 

aight truu kus for sum reason when i was at the track my car sounded like it was misfiring every thousands rpms like 6k 7k 8200 and that both wit old dizzy and the new one
