03civic When I start it either it will start or it will click.Is this a sensor,or is it the Ign. Switch,cause OBDIIsay missfire1234,corrected it,and something happens but not right away. I did notice that at low RPM it misses,.At high RPM it corrects itself for a few min.Is it Ign.switch.

 

have you checked starter? The clicking is from starter solenoid, but the contacts are probably worn out. Either replacing the starter or open the solenoid to fix the contacts.
