i just changed the wiring harness in my 91 civic and now my B16 is only running on 2 cylinders but i hooked everything back up the way it was..its my everyday car and its not runing good i need some ideas on what to do..?

 

If you have spark at only two of the four plugs, then you likely have two bad plug wires or a bad distributor cap or rotor.

 

yea man i checked the plug wires and there good and even changed the whole distributer just in case and im still running on 2.. its the 1 @ 4 thats not running..

 

Spark wires may be in the wrong order, or fuel injectors not all hooked up. Listen with a stethoscope or a piece of hose held up to your ear. You should hear the same type of clicking from each injector when it's running.

 

^^I go with checking to see if have a spark for the cylinder 1 and 4. If you do, check if your injectors are working.
