Hello I have a honda civic with the vtec. I just change the knock sensor for the second time. I can't get the service engine soon light to go off I tried resetting my computer with a computer that tell you what's wrong and I tried to unplug the battery and nothing works. I know the motor is fine. I was wondering if when the old knock sensor went that maybe the timing moved and that maybe my problem, I don't know all I know I can't get the engine light to go off. Thank you george
