so my 01 civic ex is misfiring and will lose power until it shuts off. it seems to do this only once the car is warmed up and has been running for 15-20 minutes. we already changed some things under the hood. spark plugs. ecu. crank sensor. i did the paperclip trick and pulled up a code 74 which means it's misfiring on cylinder four. what should i do? (i am complete n00b)
