In my 1998 honda civic i got engine light on. During starting it give some abnormal noise also. I check the code and find out code P0301 (Cylinder 1 misfire). I replace all four spark plug. Now engine start smoothly, but still engine light is on and shows the same code (P0301). What should i need to do. Does engine light turn off by itself? or i need to reset it with OBD scanner?

do a compression test if your code still on, the engine light will go off if the problem fixed but some cars need to reset with scanner.
