Re: Emission Q: Tricks to reduce NOx counts ? (non-VTEC)
fug, I think I have it all mixed up. Correct me if I'm wrong.
1. Retard -> rotate the distributor away from the firewall
2. Advance -> rotate the distributor towards the firewall
Also, when I check the timing w/ a timing gun there are 3 lines on the belt. The middle one is red. So, if I retard the timing which line should the pointer be lining up with? The line left (towards the fender) or the line on the right (towards the firewall)?

Yes, you must make sure that your cat is nice and hot! A cool cat does no good.
I've had hig NOX on my '95 Civic. The place that I took it recommend a full fuel system clean, including the combustion chambers. Apparently the carbon will build up in there, and somehow that will cause higher NOX levels. They did it, (It was expensive, like $90, some big machine by Snap-On), and it cut the NOX levels drastically. It allowed my car to pass!!! FYI...
