Hi guys need help ASAP! It's 1.4 civic ej9 I have new distruibtor new plugs leads fuel filter the works I changed the iacv 3 times and I'm still havin issues when I drivin along its back firing blowing black smoke and drinking petrol, I got it plugged and got a code for a 02 sensor changed that and engine light when off and came back on after while but I can not figure out what's going on help???
 
Dude if I were you I would just take it into your local garage and have them look at it. Sounds like it could be a whole range of problems and by the sounds of it you are clutching at straws trying to find a solution.
What year is your EJ9 and what engine code is it?
Have you checked any CEL (Check Engine Management Light) codes? If any have come up what codes were they?

I will try to help but I would say your best bet is to take it to a garage.
 
From what you have mentioned I would have said O2 sensor, particularly with the smoke issue. A faulty sensor will completely mess up the fueling, my mums last EP3 ran like shite, spluttered, backfired and bogged down due to a faulty O2 sensor.
 
I got it plugged in and code is for o2 sencer but I replaced it with a honda one direct honda fit from a 1.5 honda my civic is 1.4 ej9

lamda sensors are pretty temperamental things though, I would try one from the correct engine, D14A4 (Pre facelift) or D14Z2 (facelift) engine, I know when getting one from my mums car we tried an import EP3 sensor although being in perfect working order didn't respond well with the car, the correct facelift UK spec sensor solved the issue.
 
Have you checked the timing belt to see if it has jumped some teeth?
