Hey I just got my ZC put in my civic and it runs good and sounds pretty good. But its running really rich. When I stomp on the gas black smoke shoots out the exhaust and the 1st cylinder is poping out the plug wire. I had a code 4 on my check engine which was the cylinder position sensor but it went away after about a hundred or so miles. If you have any suggestions or know whats up with this let me know Im up for any advice. Thanks
