I have a 1995 Civic ex with a AEM V2 cold air intake and an Apexi N1 exhaust. I had taken the plug wires off the valve cover to paint it, but I didn't have enough time, so I put them back in and started the up the car up make sure I got the firing order right and the car ran fine.

Fast forward to now. I let my Dad drive it to it work one day and he said it was running fine then all the sudden he said it was running really bad. It sounded like a cylinder was down. I took the plugs out and the number 3 plug was black. I had thought that I had maybe pulled on the plug wires too hard when I was taking them off. So I replaced them with new ones and the problem was still there. So I replaced the cap and rotor and its there. Its down on coolant and I've got spark and the ingecters are working.

Please help me. I'm only 15 and I don't know alot about cars.

 

did you try replacing the black plug? or cleaning it? is it smoking at all?

Should I replace it? It smokes a little, but not alot. Thanks for the help man.

 

is the black plug firing? if not the smoke is probably unburnt fuel. and was it smoking before this happened?

 

I think it is firing, but I'm not sure. No, it was not smoking before this happened.

 

Does anybody think it could be the headgasket?

 

i doubt it the headgasket...start by replacing the plugs its not like there expensive as hell then go from there
