My car runs really rough from idle all the way to 3K rpms the check engine light is flashing, when I scanned the car it pulled up 3 codes for a miss fire on Cylinders 1 3 and 4. I have already put replaced all 4 coils with genuine Honda coils, new plugs new ELD senor and IAT sensor. I checked and all 4 coils are firing. Also the electrical system surges as in all the lights on the car (head lights, interior lights, and tail lights). I checked the battery while running with a volt meter and it read 14.3V which should be fine. Please help I am mechanically inclined I just do not know Honda's and would prefer not throwing new parts at the car.
