#302071 My civic has a random misfire and kinda feels hesitant when a light load is out on the throttle or when you punch it. I can't figure out why
My set up is b16a2 head and intake. Gsr bottom end.
I've changed out the icm. Coil pack. And button and cap. Has new wires and spark plugs. Adjusted ignition timing to see if it had anything to do with it.
What's weird is it doesn't always do it. Maybe 1 out of every 5 time I drive it the car runs smooth with no misfire or skip. Whether its been warmed up or it's first run of the day.

Anyone ever seen this? I don't know what else to try.
