I have a 93 honda civic dx with a Vtech from a 98 intgra gsr... headers, exhaust, intake, short shifter, blah blah.... anyways.

When I get on my car black smoke comes out, and when I take my foot off the gas too shift or too slow down, it has a little back fire.. and some times.. I dont hit V-tech in first gear... it sounds like I do... but I don't go much faster.. these seems too happen when my car gets hot. I need too pass emisions as well.. and I think this is probably the reason Im not passing

 

sounds like your car is running rich

Yeah which part of the test are you failing?

 

I hope that there are still people interested in this topic because I am having a real hard time with my 99 civic ex. Recently I bought the entire suspension of a 00 civic si off of ebay and I decided to switch out the rear brakes first on my 99 civic. I had tried this once before with the rear brakes of a integra but then I was riding for a while without the right e-brake cable. So intead I bought a whole new suspension to try an eliminate all the problems I had.
Now that the rear suspension is changed I can feel the rear shift whenever I hit a bump and when I go over 40mph in the rain. I have no idea what was done wrong, I did not do the work myself because I had no time therefore I do not know where to look. Has anyone ever had these problems before or know what might have been missed?

Please help!

Hi CO means your running rich.. Maybe Something is restricted with your air? Also you have high Nox.. Check your EGR .. By any chance do you have a vtech controller?
