so this weekend I changed wires plugs & fuel filter & now my CEL stays on... not throwing codes just stays on but runs perfect... any ideas? I checked all CEL threads but coouldnt find one on the CEL light staying on...

 

are the plugs gaps correctly? maybe something wrong there? or did you try to reset the ecu and see if that helps?

 

I got some iridium NGKs & was told by the guy at autozone not to gap or ill destroy the contact I havnt reset the ECU yet either but I dont know how to either this is my first civic n I just got it a few weeks ago. thanks for the feedback
