I'm merging onto highway and if i rev over 6k. After it my car will studder and won't go. I'm on the throttle but the car studders and then takes off and studders again and takes off again. Have anyone ever had this problem? If so please tell me how to resolve this. it's a b18b swap into ek hatch.

 

94 civic ex here. fuel filter on mine had to be replaced due to that nature you're describing. distributor, spark plugs, spark plug wires, oil? check to see.

search up fuel filter and you'll see others complaining about the same problem. or search "studder or bogging"
