And the journey to passing emissions continues...

Turns out the person I purchased my civic off of had the timing advanced pretty high. We found this out last week before I did my second emission test. However, after putting the timming back to stock setting the car still failed, so the problem did not only exist in the timming itself, so it seemed.

We did notice however, after about a day after setting the timming back to stock level it was a bit hard to start and even worse when the engine was hot. After a few minutes of trouble shooting yesterday, the car would not start.

So we looked to the distributor as the culprit, because the engine would "turn over". After examining the distributor, it seemed to be ok, so we figured the distributor coil that was dead.

I beleive the timming was so advanced because the ignition coil that recently died was on its last "ball hair" so to speak. After we replaced the distributor coil mechenism with a new one, the car started like perfect.

I was just wondering if this would have a major impact on my emission problem? (High Nox ppm) ----> A bad distributor coil ?

And would it be a good idea to retard the timming below stock level before go to get the next emission test done?

I am not sure if this is the maim problem, because I was being told that it was most likely a vacuum leak...

My engine "d15b7" does not have an EGR valve, so this is not causing any of my problems.

PCV valve is working perfect.

Hope to god that my problem is solved by the fautly distributor coil....!!!!!!
